Obviously you should relearn everything. Heck, pick up the Dvorak or Colemak keyboard layout while you’re at it!

That toshy thing looks like the right way to go. Wild that this is such a complex issue.
I had to go the other direction (Linux -> apple) for a bit and ended up remapping the caps lock key to command so I could approximate “normal” reflexive (pinky-based) shortcuts. It did sort of simplify copy-pasting in terminals.
I can’t even get mdns to work with systemd-resolved and a local VM.
Best of luck though, definitely something I’ll be watching!
