One thing that helped me make the transition to nearly full time with the Mac was remapping Command. I remapped Command to Control, and put Control on the Meta / Windows key (I mostly use an external kb).

This kept my decades of muscle memory almost intact since I'm so used to Control being the primary modifier in Linux and Windows. And, weirdly enough, it helped me learn the new MacOS shortcuts since the patterns were now centered on Control instead of the Command key.

You can make the switch without having to use 3rd party software. The Keyboard section of Settings will let you adjust the modifier keys on a per keyboard basis. With different settings for internal, external, etc. if you wish. And it will let you remap Caps Lock if you prefer that to be something else.
