I must say I had the same feeling. For me personally, who hasn't been a PC in about 25 years, it is very overwhelming and has lessened my desire to play.
You should be ok. Nice thing about PF2 is you can't really make any mistakes. Even in 4E you could make mistakes choosing inferior powers. In PF2 you can make a poison rogue, a thug str rogue, or a dex rogue and be relatively equally effective. Or a 2 weapon ranger or an archer and be just fine. There aren't many choices you make that will make you suboptimal.
In PF1, 5E, or even 4E, you had to force the character idea to fit the powers. In PF2 you can write a character you want to play first, then figure out what powers or choices will let you play it without feeling like you made sub-optimal choices. If you write down I want to be a knife throwing former circus performer, you can build that fairly easy.
PF2 really reinvigorated my character building, which I really enjoyed. No more orc warlord-elemental bloodline sorcerers with empower spell and quicken to make the super damage dealing sorcerer. Now I built an ancient elf sorcerer with the undead bloodline who was stillborn and raised by a wizard father who brought him back with arcane magic that manifested within the character as the ability to channel positive and negative energy to destroy his enemies while multiclassing as a wizard to show the wizard training his father gave him. I made a blue dragon instrinct drow barbarian wielding a Falchion whose sword crackles with electricity when he rages. Yeah, you can make an elf barbarian even with the -2 Con and be just fine. I made a stormborn half-elf druid whose mother was struck by lightning while pregnant who also has a affinity for animals. You can literally make any concept you feel like making and can find the feats to make and not feel like you short-changed yourself. That is a huge change over 5E, PF1, or any edition of D&D I've played in the past except maybe Basic/Expert D&D where you had very few choices.
I was so tired of having to play a 2-hander weapon user in PF1 or 5E to be a decent martial. Or a magus using shocking grasp. Or a caster taking the same feats every time to maximize my power. Or having to deal with master summoners. Or in 5E choosing a 2-handed weapon user with GWM or an archer with Sharpshooter or make some Paladin Multiclass with smite or a sorlock as a caster while having a bard with bless to optimize the group. Watching my players unable to find optimized ways to build characters and feeling like they can make any class any way they want to make it has been incredible refreshing in PF2.
Now that my players can't find the optimal way to play, they just try different things depending on what catches their interest. They don't focus on weapons with better crit ranges or ability enhancing magic items or classes with the best feats or any of that. They just read the classes and go, "This looks interesting. Let me give this a shot." They find that no matter what they pick other than wizard, they are fun and effective.
