Some additional bits to the other answers
The big thing that ended up turning me off was leveling. I hate leveling in this game. Every time it's dozens of spells, dozens of feats, all of which sound equally unexciting even though I know picking the wrong one is liable to turn the game into an unplayable mess somewhere down the line. Multiply that for however many characters.
Some levels require more choices than others, usually there's more at the very beginning. After that, the choices become less abundant, and you also know the game better, so they are easier to make.
Personally I find that fun and exciting to see the new toys I'll get when I level up, but I admit that I was a bit lost the first time. I took the Pathfinder Core Rulebook (1st edition) and looked at the races and classes that appealed the most to me, that helped me get a little more knowledge for those early choices. You don't need to do that of course, with a party of 6 there should be enough redundancy to forgive non-optimal choices. It probably depends on the difficulty level, but you shouldn't be afraid to select what you like most, do you prefer melee or ranged attacks? Two small weapons, or a big heavy one? You'll do fine, either way.
Important regarding your companions: you don't have to micro-manage their career! As long as you keep the default choices, they will only require you to click once for final approval. If you modify the default choices (by getting back on the character sheet), I think you'll have to continue manually from that moment on, for that companion. I think that's what @Pladio; mentioned - perhaps it also works for the main character.
Please someone hit me if I'm wrong
Have a look at the
Bag of Tricks mod, it provides you with a respec ability (to be used with caution), in case you made a very big mistake. Cherry on top, there's a camera tool, allowing you to rotate the camera, and extend the zoom range
Camping! This is not unpleasant, just confusing. I try to go as long as I can without doing this, because of the time limit on quests. The problem is that I have no idea why sometimes camping seems to work better than others.
Just to make sure because I had this issue: there is a button at the top of the first screen when camping, MANAGE. It's easy to miss, the colour choice is such as I hadn't noticed it at the beginning
If you hit the button, you can assign party members to the posts @purpleblob; has detailed above. When you grab one of the avatars, the game will show their ability for each post. The cooking has a DC for each meal, which makes some easier to succeed than others.
In dungeons, you have to bring rations, again you need to specify that in the camp management screen at the top. If you don't use rations, resting will not restore much, it will only be considered as a short pause (it should warn you about that, also saying hunting is not possible).
You can buy those rations, they are cheap but heavy. As in D&D 5E, the purpose of this "cost" is to avoid people resting all the time in dungeons to refill.
Ranger was fine at first, but it started getting kind of boring later on. I'm thinking of rerolling with a different class, but I'm naturally weary of that because of issue #1. Is there a class that maximizes fun while minimizing crunch? One and the same, really.
I had a lot of fun with a rogue / eldritch scoundrel. But to each their own, really.
