Crouch jumping is a thing I had to consider for rocket jumping in TF2, and I never find myself aiming while crouch jumping, so pressing down on the right pad to do it worked out nicely for me. I used the bumpers to scroll through weapons at first, as well, but eventually I had to switch over to touch menus due to games demanding more inputs.
Heyyy, I just started Max Payne, too. It feels great with the Steam Controller, though lack of analog movement makes me sad. My uploaded binds are similar, but the touch menu is on the right pad through a right bumper mode shift. It really helped me out a lot in situations where I have to keep moving away from enemy fire., since otherwise my left thumb would be occupied picking a weapon.
