Depends on the game. Most common setup is just mapping the ABXY buttons to them, so I don’t have to take my finger off the right thumb stick to press them. In Elden Ring I use them for dpad presses instead, because I need to cycle spells/use recovery items without stopping moving.
I know a lot of people use them for L3 R3 instead of clicking the sticks.
In a couple games with smaller text I use one for toggling the magnifier, or in keyboard heavy games for opening the keyboard.
