Since you have FileMaker Pro Advanced, Select Database Design Report from the Tools menu and select only the Accounts option from the check box list of report options.
That will list all accounts with associated privilege sets and then will list a privilege sets and their settings.
If that is not quite sufficient, there are several 3rd party tools that use the xml form of this report to analyze your report in even more detail, one of them may offer a bit more in this area.
Wow! That is seriously cool! Thank you, Phil!
