I mean, all of this is available in MacOS as well, and configurable even—your main complaint seems to be that it works differently from Windows?
MacOS is a different operating system with different paradigms; instead of a start menu, you'd use Spotlight search for the same effect, which can be invoked with CMD+Space.
No, the main complaint is that you can't do half of those things with a keyboard. Eg. how do I maximise a window on macos with my keyboard?
I have been using macos for decades and use it daily at work so I understand it is different. I am just saying that the out-of-the-box functionality for keyboard usability is very poor compared to Windows (and Linux DEs which imitate Windows).
I end up using Rectangle on macos for moving windows and maximising them using keyboard shortcuts because else it's infuriating for window management to have to move from the keyboard to the mouse all the time. The usability under Tahoe for window edges etc. is even worse with a mouse than previous versions and a complete joke, so I am stuck on Sequoia.
