I just meant are there extra models and stuff in the extracted pak file that I didn't have access to before extracting them? Like what assets comes out of the pak files besides scripts that I wouldn't have had access to before?
I hate to say it again, but it depends on the .pak. Normally, you extract Shared.pak for the scripts, but if you want anything else, you're going to have to look for it. If your interest is in art assets, I don't do anything with art, so you're better off asking someone who does. That said, you might also be better off just solving problems as they come up, rather than trying to deduce what you could possibly might need in the future from the .pak files. They're always going to be there.
