I left Colemak for Qwerty some 5 years ago. Keyboard layout matters much less than your typing technique.

Same thing for ergonomic keyboards - they can be a dangerous sign that you're focusing on the wrong thing, on micro-optimizations rather than on the root cause.

I have no guide to share unfortunately but I'd recommend observing one's movements, and try to figure out what's the most natural way of doing a given thing.

Also, regardless of what you do, typing many hours will tire you / be painful. Act accordingly.

I disagree. It depends on the keyboard, of course. For example, the Microsoft Natural I had in the 90s was a complete POS that exacerbated my tendinitis. It was a cheap sliding-post keyboard. If your finger hit anywhere but dead-on, the resistance was tremendous.

A good mechanical keyboard will provide perfectly consistent resistance, which will be a huge improvement over a poorly designed, cheaper keyboard.

A more advanced option like the Kinesis or Ergodox completely eliminates many of the fundamental problems with traditional keyboards that create pain in the first place.

I went for a kenesis advantage and it solved all my problems. I think a big part was it forced me to type better. It’s too hard to use the wrong fingers.
