I wonder if it works, but Double-clicking the top Bar of the Window could maximize it?! Idk if that's a MacOS Feature or if "Tiles" gave me that function.
For any Window Management Apps, there are things like Better Touch Tool or Magnet, they cost Money once.
There are free options as well. I use Tiles:

It's Universal, so it runs native on every Mac. It will either "snap" into position, or you can use shortcuts to make the Window snap imediately into your desired position.
Or another free alternative, Rectangle:

But especially on a Mac, i do recommend using at least 2 Spaces if you Multitask. That 3-finger-Swipe between spaces works extremely well, that makes using spaces very nice (i can't use multiple Desktops on a Windows 10 Notebook, it feels super clunky).
