Newish player looking for help

Ok, so im new to pf2e but not ttrpgs, i want some recommendations and tips for character builds, the ones I already had in mind where a throwing giant barbarian, or a ranged weapon thamathurge. I haven't even begun to look at casters but I would like some recommendations on which casters are fun but also not super complicated, i do optimize and min max so if you guys have build paths let me hear them!
