I use dictation on my MacBook Pro liberally. One thing I wish is that my Emacs interacts with the Voice Control features - Voice control does not recognize the Emacs on my Mac at all.
Also, Karabiner-Elements helps me to remap some of my awkward key combinations. For example, I avoid doing any typing with my pinky - so shift has been remapped to spacebar long press, and control has been remapped to caps lock. These are standard settings that I think many people use.
I also try to use text-to-speech and voice control to avoid pressing the ridiculous arrow keys on the MacBook Pro.
On other machines, I have an easier time, since I have bought a mechanical keyboard which supports softer keypresses.
When I finally come around to it, I will try to purchase a joystick/accessibility (vertical) mouse. I just don't want to clutter my small desk too much.
Not OP, but I periodically swap my mouse hand, and that seems to be enough change to ward off my long-standing wrist issues. That and a proper mechanical keyboard with decent travel in the key stroke are necessary for me to do this long term.
