I use default, except for Z, X, C, being 7, 8, 9 hotkeys
I have F as perspective change
I use my mouse's side button to sprint, but not all mice have a side button so idk if it works for you.
I would also recommend tinkering with ur video settings, you may want to turn off things like fancy graphics. I specifically recommend turning off screen animations tho since they make chests UI pop up instantly instead of sliding into frame. Also having a GUI scale modifier as -1 requires you to move mouse less when looting chests. As for FOV and sensitivity, its really up to you.
