I did the transition around 8 years ago. I wouldn't say I was a power user in Arch, but used i3 as a window manager and lived mostly in the terminal.
However for a job I got a Mac and it wasn't really hard to get into it. There is a terminal application and you can basically install most Linux tools. I got used to the Mac and enjoyed that everything is working out of the box, like connecting external devices. I could use my work Mac for personal usage and after some time I abandoned my Arch machine.
I also don't use Docker extensively, but I sometimes have to create a container and so far didn't have any problems with it. I'm not having an M1, so no clue how it is with that one.
I'm still on Mac and don't miss the Arch days, where I had to compile some packages and install drivers manually. Also I don't use any Apple tools, like iTunes or so, and therefore I'm not locked into their ecosystem.
