I know I'm later than the GTA 6 release but i just wanted to mention how you can bunny hop on a controller. I set my keybinds for jump as down d pad and r1 as sprint. I would use my left middle finger to jump and left pointer finger to move forward. I would use my right pointer finger to sprint and let go of it. And I would use my right thumb for moving my camera. Its not that uncomfortable and it works fairly well. You need some practice for it to be perfect.
