I use homebrew as it has good list of package formulas. You can also check out macports.
Colima is a must if you run containers.
Command key instead of control for shortcuts.
Cmd-, app preferences
Cmd-c/x/v for copy/cut/paste
Cmd-shift-4 to capture part of screen (draw a box). Press spacebar to change to window screenshot.
Enable tap to click and extra gestures for the trackpad if you have one. Multi finger swipes are very useful.
