It's really easy so long as you a) start at level 1 or 2 and avoid building out too far ahead, b) build to a character concept rather than try to optimize mechanically, c) avoid options released in adventures. Oh, and d), understand that retraining is actually baked into the rules.

Adventure character content is less rigorously tested, and mostly amounts to professional homebrew. It's often super focused on the scenarios presented in the adventute and significantly less applicable in general.

Focusing on mechanical optimjzation rather than character concept often leads to madness, since feats are generally well placed within the same power bands (there are few stand out or trap options). For a crunvhy game, it's often best played descriptively.

Characters become mechanically more complex every level or two, so starting at higher levels can be very overwhelming for new players. Building out a higher level character means choosing a lot of feats, and often the utility of those feats is only really understood through play.

Much better than 1st edition, less feat trees (more pools or tracks) and those that are there have less dead ends. I feel like there are less feat traps than 5e proportionally but I am still learning the system myself.

I'd say it's not terrible if you have some experience with TTRPGs and use Pathbuilder (a free character-building site/app). That said, I obsessively research and follow guides while making my characters, so I might not be the best source on vibes-based character creation.

you do not have to worry about anything other than what you'd like to play. you could do everything randomly and you'd still make a pretty good character

Just play a fighter/rogue. Best way to learn pathfinder 2

While there are some dead-end builds, they're pretty rare. As in, avoid the toxicologist subclass for alchemist and you're largely fine.

There are some classes I wouldn't recommend for new players due to complexity, like the alchemist and the psychic, but that's only because they're complicated.

Another thing to keep in mind is that martial and caster classes are actually balanced against each other now, and melee characters are going to do more damage than ranged characters due to them being on the front lines and taking more risks. This isn't critical for effective gameplay, I'm just trying to let you know what to expect.

While you go about making a character in Pathbuilder, I recommend also looking up the same options in Archives of Nethys, which is the semi-official source of game rules. It will have everything available on there except for adventure paths and lore books, with the full text of every option and rule. There's chapters available on there on how to play the game and I recommend reading it.

Another reason to use Archives of Nethys is because it gives more context on options. You could build a character that is a rare ancestry like a Conrasu or Goloma, but without a picture and full description you're not going to know what your character actually is.
