I’m in the same box, I’ve tried Box Jade, Holy Pandas, MX Brown, Gateron Ink Black, Topre, MX Blues, Tangerine and Gateron Ink red. I also add some test switch zealio, etc…
But my favorite switch and daily driver are the gateron ink reds because they are so light.
The bigger problem is not the layout it’s the keyboard itself, if you have rsi switching to an ergodox can improve the situation, if this is not enough something like a dactyl manuform or a kinesis advantage 360 should do the trick.
This combined with light switches like tactile (MX brown) or linear (red) will reduce your pain immensely.
