House rules in your home games

What modification of PF2e rules does your group run? For context, I'm involved with running one group on Mondays and a PFS series of games on Saturdays. Currently looking for useful rules to use on the Monday games as they're a bit looser with the rules.

A couple of the PFS GMs have decided that Pathbuilder 2e isn't random enough and doesn't do crit damage right, so have banned it for their sessions, which is a pain for my disabled brain.
