What facebook user data is accessible through the api of it only with an application access token?

I'm participating in a project in college and I need to use facebook's api to try to collect some data from facebook users, but I've already faked the api documentation a lot and I still do not know what data I can access using an access token of the application, the idea is to see what data I can get without the user's authorization, has anyone ever done something like that? Or have you used the api and know how? I plan to do everything using python.
