1. Free Archetype
Are there specific Archetypes I should be restricting due to issues of balance, or are they all reasonably balanced? Any that I should keep my eye out for to ensure they don't break my game?
I don't think there's much of a balance concern with Free Archetypes. For the most part, they allow characters to do more things, but not be much better at the things they already do.
There are a couple of exceptions, with the fighting style type archetypes, where maybe martial characters end up getting all of the class feats they would want instead of having to pick and choose. Even that doesn't seem like a huge deal, though.
My personal preference is to dictate a couple of choices for a character's first archetype, then let them choose freely once they've taken the required dedication plus two additional feats. Typically, any restriction would either be based on some sort of shared background for the campaign, something I thought was particularly appropriate for the background they came up with, or maybe just anything from the "Profession" tab on the Archives of Nethys.
I don't think you'll break anything if you just give them free rein, though.
