Yep, as someone who's gotten really really dependent on app Exposé on macOS... it's hard for me to switch to a keyboard for things I'd rather do on the trackpad!

I do have to agree, though, that macOS window management can feel a bit clunky using a mouse and keyboard. That's a user story that the macOS UI/UX team ought to look into, it wouldn't be that hard to create some decent bindings in the OS itself.
