Here are some shell scripts to help arrange windows without having to drag them with the mouse.
The scripts use xdotool and wmctrl to move and resize windows, the scripts work with multiple monitors as long as they have a similar size screen.
If you want to use different size screens, you are probably has to design a function to calculate the correct x-axis offset.
I made the scripts using 1920x1080 resolution, higher or lower resolutions might need to tweak some values.

Key binds
You just bind the shell scripts using the XFCE keyboard menu. You can bind the shortcuts as you like, I use the super/windows key for the shortcuts.
super+q : top-left
super+w: top
super+e: top-right
super+a: left
super+s: center
super+d: right
super+z: bottom-left
super+x: bottom
super+c: bottom-rigth
