According to Sitecore best practices, presentation details should be set on the standard values of the template that defines the item. This way, all items that are based on the same template will inherit the same presentation details, unless they are explicitly overridden. Setting presentation details on the standard values also allows resetting modified item presentation settings to default values. Setting presentation details on the individual items is not recommended, as it increases the maintenance cost and complexity of the presentation layer. Rendering parameters are used to control how renderings function, not to designate layouts. Standard template is a base template that all templates inherit from, and it does not have any presentation details. References:

The field helper is a Sitecore MVC helper that renders the content of a field in the view. It also enables the field to be editable in the Experience Editor or Horizon. To prevent a field from being edited, you can set the editable parameter to “false” in the field helper. For example, @Html.Sitecore().Field(“title”, new { editable = false }) will render the title field without the editing capabilities. This parameter overrides the default behavior of the field helper, which is to render the field as editable if the page is in edit mode. Setting the editable parameter to “false” can be useful for fields that are not meant to be changed by the content authors, such as system fields or fields that are populated by code. 

The serialization command is part of the Sitecore Serialization plugin, which is an optional plugin that you can install to use the Sitecore Content Serialization (SCS) system. The SCS system allows you to serialize and deserialize Sitecore items as YAML files in your project folder. To install the Sitecore Serialization plugin, you need to run the following command in your command prompt:

dotnet sitecore plugin install Sitecore.Serialization

This will add the ser command to your Sitecore CLI, which you can use to perform various serialization operations, such as ser pull, ser push, ser watch, and ser status. You can also use the full form of the command, which is serialization1.

If the serialization command is not available, it means that you have not installed the Sitecore Serialization plugin, or you have not executed the dotnet restore command after installing it. The dotnet restore command restores the dependencies and tools of a project2. You do not need to restart your Sitecore instance or reinstall your Sitecore Content Serialization tool, as these are not related to the availability of the serialization command.

 The sitecore.json file is the project configuration file that contains several properties, including a modules property that references the relevant Sitecore Content Serialization modules. If the path of a specific module file is not set in the modules property, the SCS system will not be able to locate and access the module file, which contains the items to be serialized. Therefore, the paths and related items included in the module will not be serialized when you run a push or pull command. This can lead to missing or inconsistent data between the Sitecore instance and the file system. References:

A static placeholder is a placeholder that is defined in the layout file using the @Html.Sitecore().Placeholder() method. The placeholder key is a string that identifies the placeholder and must match the placeholder key of the renderings that are added to it. To add renderings to a static placeholder, you need to edit the presentation details of the item or its template’s standard values and select the layout that contains the placeholder. If you cannot see the “main” placeholder key you added to the layout, it means that the current template is not associated with the correct layout. You need to change the layout to the one that has the “main” placeholder key defined in its layout file. References:

A multilist field allows a user to select multiple values from a list of items. The list of items is determined by the source property of the field, which can be set to a root item, a Sitecore query, or a treelist parameter. The source property controls the items that appear in the selection list for the field. Therefore, setting the field source for the multilist field is the next step after creating the field as a multilist type. References:

Image is considered a complex field in Sitecore MVC because it requires additional parameters and logic to render properly, such as the image source, width, height, alt text, and so on. The Html.Sitecore().Field() method is designed for simple fields that only need the field name and value to render. For complex fields, you should use the Html.Sitecore().Rendering() method instead, which allows you to specify the rendering parameters and the rendering item for the field. Alternatively, you can use the Sitecore MVC helpers, such as @Html.Sitecore().Image(), to render complex fields with more control and flexibility. References:

A placeholder key is a unique identifier that is used to refer to a specific placeholder in the presentation details of an item. A placeholder key is defined in the placeholder settings item that is linked to a rendering or a sublayout. A placeholder key can also be defined in the code or markup of a component. A placeholder key can be static or dynamic. A static placeholder key has a fixed value, such as /main. A dynamic placeholder key has a variable value, such as /main-{GUID}, where {GUID} is replaced by a unique identifier at runtime. Dynamic placeholders allow multiple instances of the same component to be added to a placeholder without conflicts. References:

This answer is based on the Sitecore best practice of using template inheritance to avoid duplication and ensure consistency. Template inheritance allows you to create a base template that defines the common fields and then create other templates that inherit those fields. This way, you can reuse the same fields across multiple templates and avoid having to update them individually if you need to make changes. Template inheritance also helps you to organize your templates in a logical hierarchy and reduce the complexity of your data model. References:

To implement a layout in Sitecore MVC, you need two things: a layout.cshtml file and a layout definition item. The layout.cshtml file is the Razor view that contains the HTML markup and the placeholders for the renderings. The layout definition item is the Sitecore item that references the layout.cshtml file and provides metadata for the layout, such as the name, path, and device. You can create both of these from Sitecore Rocks or from the Content Editor. References:

 Workbox is a Sitecore application that allows you to view and manage items that are in a workflow. Workbox displays the items that are in each workflow state and the commands that are available for each item. You can use Workbox to perform workflow actions, such as approving, rejecting, or editing items. Workbox also shows you the history and comments of each item in a workflow. Workbox is useful for content authorsand editors who need to review and publish items in a workflow. References: Sitecore 10.0 Developer Documentation - Workbox

Standard values on data templates are used to define default field values, default settings, and insert options for a data template1. They appear in the content tree as a child item of the data template called __Standard Values1. When a new item is created from the template, it inherits the standard values for its fields. If the value of a field is NULL, the item contains the standard value for that field as defined in the data template2. This way, standard values provide the default values for fields when a new item is created from the template and a fallback value when fields are left NULL2. References:
