it isnt perfect, but with BetterTouchTool you can toggle resizing -- e.g. three finger double tap on a trackpad, move your cursor around to resize, double tap again to exit the mode.

I use Yabai, which is pretty good -- and you don't have to completely disable SIP.

For moving windows around (floating if using Yabai), I just hold HYPER and move my cursor around (Start Moving Windows). Release HYPER and it stops.
