It's probably not very useful to ask for too much, in a generic manner. My approach is to ask about what is not obvious or answerable by reading the privacy policy. For example source of particular data point that I have not given myself (like phone number, etc.), and that is not publicly available. Most of the answers to questions in the access request are usually available on the comapny's website already. And if you send generic sounding e-mail, you'll get a generic reply to read the privacy policy.
