Hyperdock is one of the best purchases I've ever made. It allows you to assign hot keys to window management - e.g.
alt-left-mouse: grab anywhere in window to move
option-command-left-mouse: resize window from anywhere in window
Hasn't been updated in years but it still works on Monterey though it occasionally requires some kicking. I've looked for alternatives that are more up to date but can never find one that does the above - it's really all I want in a window manager as I don't like automated tiling and other features.
