A family of Microsoft word processing software products for creating web, email, and print documents.
The Name parameter is the name of the Document Property you want to reference.
There are a number of document properties built into Word documents and you can create your own. Sharepoint can also add properties that respond to this field.
If you are using one of the properties you can find under Quick Parts, you might as well use that instead of a DocProperty field. It is quicker and you can change the property by typing in the content control. Repeating Data Using Document Properties Content Controls and Other Mapped Content Controls
Look under File Info. On the top right should be a drop-down for properties allowing you access to advanced properties. A dialog will pop up. Some of the built-in properties are shown on the summary tab. Custom ones would be under the Custom tab.
You could compile a list using a macro. See https://wordmvp.com/FAQs/MacrosVBA/MixedDocProps.htm.
The following is a list of the built-in properties. Some are read-only.

Not all of these are accessible using the DocProperty field. The ones shown in the dialog box can be displayed in the field. Some can only be reached using vba.
If you were using any that have spaces in the names, you would need to enclose the name parameter in quotation marks.
