Personally thumb + C and thumb + V on apple keyboards always felt a lot easier than pinky finger + C and pinky finger + V which just felt and still feels weird.
Cmd+Shift+T is fine to hold to re-open a tab, but Ctrl+Shift+T makes my hands hurt on a regular keyboard. It's also annoying to have to switch between Ctrl+C to copy in normal apps, but in a terminal that would cancel the command, so you have to do Ctrl+Shift+C there. On a mac keyboard it's always the same. I've tried to use e.g. autohotkey to get the same consistency but it's rather annoying (need to inspect which window is active, sometimes doesn't work).
