I've been a Linux user for the last ~15 years, and now I need to do some iOS development so just a few days ago I've ordered a Mac Mini. I guess I'm in for a bumpy ride. Oh well.
If you had different preferences, mostly too bad. Maybe if you reboot with system protection turned off, you can edit the config file, and hope it doesn't get reverted.
If things didn't work, like when I was getting static for audio 25% of the time I hit Play in iTunes from a shoutcast server for a whole major release, there wouldn't be any useful help on the internet. Maybe somebody had a similar problem 3 releases ago, but that fix doesn't work anymore. Other problems, or irritants are often the same way.
With Windows, most of the problems you run into are fixable, and easy to find. With an open source OS, at least you can dig in and try to fix your own problems.
This doesn't help across applications of course, and there's a reasonable argument that the inconsistency is worse than the absence -- but for me, iTerm2's FFM feature helps.
You just mean that hover over a lower window allows scrolling right? MacOS has that.

I use Amethyst which is much easier to setup than my old Linux WMs. There are also tools like Yabai which are more customizable.
I recently made the transition (from ~10yrs Linux) to Mac and it was really smooth. At the end of the day it's just a Unix system with a really nice looking Window Manager and lots of supported apps. If you don't like the included version of SSH, just use a different one, same as linux.
