The Keychron K4/related (K4 HE here) compact 96% layout is definitely my favorite keyboard layout. Just a solid brick of keys.
I've been using a narrow keyboard and ergonomic mouse for 2 weeks, and my shoulder pain is starting to go away.
I put a number pad on the left and it's much easier to key in numbers with my left hand instead of using my mouse with my left hand.
It's insanely compact for a 96% board.
