EDIT (2024-08-10T19:23Z): I should clarify that I am referring to the layout that you use for a physical computer keyboard, not a mobile/virtual keyboard.
Dvorak. The same as others have posted, I started to type for a living and started to feel the numbness in my hands as I read up on RSI. I switched to Dvorak on my phone then eventually to desktop.
I'm willing to take a gander at the Workman layout.
