Basically, it could be anything that is VBA-compliant. Some you've missed out include the following MS-Office objects:
CreateObject("Outlook.Application")
CreateObject("Access.Application")
CreateObject("MSGraph.Application")
CreateObject("Visio.Application")



Other common ones include Adobe Acrobat Pro objects:
CreateObject("AcroExch.App")
CreateObject("AcroExch.AVDoc")

Then there are others, like:
CreateObject("ADODB.Recordset")
CreateObject("ADODB.Connection")
use for database queries, and:
CreateObject("Scripting.FileSystemObject")
