I've been on a mac for ~4 years now. It was a bit of a struggle to get used to it, coming from windows. The only thing I really miss now is alt-tab working as expected. (It's a massive pain to move between two windows of the same program)
You know you can use CMD+backtick (CMD+`) to cycle between windows of the same app? Add shift to go in reverse. Or otherwise you can enable the app exposé feature to swipe down with three fingers and it will show you only windows of the same app.
GNOME does this much better, as it instead uses Super+. In the US, that remains ` but elsewhere it's so much better than on MacOS.
