I am currently developing some forms in Nintex (formally in Infopath).

Most fields/columns are not an issue, but I want to include items like “ID” and “Created By” in the Edit/View versions of the form. 

They do not, however, populate in the list columns section to be added to the form. They are available for creating variables in workflows, but I do not know how to make these viewable on the View/Edit views of the form.
