Which classes should I take?

you should look at the colleges you want to apply to and see if they accept ap world as elective or core credit. my counselor told me that if you take an ap that's super related to your major they might not accept it because they want you to take their version

I would recommend taking CIS Spanish 4. It's a Very Prestigious class to be taking because of all the prerequisites it has, and it could help you get that Seal of Biliteracy. It's usual to not take an AP class close to your Pol Science Major because, in college, if they accept it, they will give you a more difficult version of the class (lowering your GPA possibly).
