Sorry having to use ctrl+shift for in a terminal is absolutely awful. macOS keyboard shortcuts are king.

agree. I guess it's a force of habit, but I am so used to the cmd+<whatever> (specially copy & paste) shortcuts, that I configured them into my linux desktop to behave the same way

Being limited to just control and alt definitely cuts down on the options. Conversely, having MacOS command key act as “super” in Emacs opens up some possibilities.
