Hello,
I have been scattering objects on objects for more than 20 years now, and for this I have used literally every tool and software that existed throughout the years.
Blender particles and vertex / face instancing were a half solution, a workaround.
The implementation of geometry nodes made it fun and pleasing to scatter things with Blender for the first time.
So I gathered all my scattering experience, favorite options, test cases and methodology and I made this geometry nodes setup 
It can be used to scatter polygons on polygons. Abstract, plants, nature, rocks, buildings, antennas on buildings, whatever.
