I use Bettertouchtool's window arrangement functions which you can set to (nearly) any custom shortcut you want. I use these on all applications not just Finder (in some it will not work) and I use these all the time.

my laptop:

- fn + left middle double tap -> position/maximize window to half left screen

- fn + right middle doubletap -> position/maximize window to half right screen

- fn + top middle doubletap -> maximize window

on my desktop workstations I use keyboard shortcuts.

I also use BTT, but just drag the window to the left/right/top edge of the screen accordingly. Turns out that's enough for me so I even stopped using Moom which alows more flexibility.
