This is all fine for some, but i am happy with most personalization options provided by windows 10. The only thing missing is the ability to close window by middle clicking on its taskbar item (common, we can already close browser tabs this way, it's common sense). In window i use a taskbar tweaker app and i wasn't able to find a similar setting for Linux.

Probably even more annoying is how linux desktop hijacks most hot keys. I use Pycharm and couldn't use any key combinations that involve ALT key because somehow Ubuntu thought that key should be dedicated to moving the window. I eas not able to find a place to disable it. This was back in (or before) 2018. I haven't really tried linux as a daily driver since then.

Do you think they had green with very poor contrast from the start? https://coolors.co/contrast-checker/ffffff-65c466

I highly doubt it. Apple is known for intentional design.
