Funny enough I use Colemak with my ergonomic (split, columnar stagger) keyboards only, and qwerty on mobile (and on my laptop since it has qwerty keyboard labels).
I recommend, in order of increasing effort:
- briefly learn touch typing but then develop your own style with a more relaxed wrist position that de-emphasizes excessive hand movement, uncomfortable movements and crazy pinky stretches
- get a columnar stagger, split keyboard
- learn colemak (I like Colemak DH)
It was a real game changer for me. If you combine it with layers for accessing numbers, arrows, symbols, home/end etc without moving your hand, it makes typing so much comfier and faster
