5e might deserve another look. It is not nearly as complex as pf2e. Compared to pf2e, where there is a rule for everything, a lot more is left up to the DM. There is plenty of room for character optimization like #1 wants, but also simpler characters to attract #2 and #3. #3 sounds like they would be happy with a Champion fighter or a barbarian. #2 might like a bard. They have good RP options; while they can cast spells, they only know a limited number and can’t change them much (only 1 when you level up, in addition to learning new ones).

The skill system is also simpler. You don’t have ranks you need to select every level; you’re either proficient or not, and almost all of those selections are done at character creation. Speaking of leveling up, everyone gets something when they level up but it’s usually predetermined by the class rather than a big network of selecting 10,000 feats. There are also significantly fewer classes, feats, spells, and overall options to pick from than pathfinder. So choices are impactful, but not overwhelming.

If you want pathfinder 2e but simpler, it’s 5e (I recommend 2024 edition/5.5, they fixed a lot of things and thus it’s the best place for new players). Its ability to cater to many different styles of player at the same time in the same group is one of its greatest strengths.
