I feel like pf2e has just enough rules to empower the players to the level I like

The more DM fiat a game has, the more trust I need from my players for things to go smoothly.

That's not a bad thing, necessarily, but for me structure is usually good as long as it doesn't raise the skill floor too high.

Once I've got trust built and feel a bit more experimental, I like Dungeon World or even Universalis
