I would also imagine that in addition to those three, regular old-fashioned attenuation would degrade the signal at significant enough distances as well, no? Or is that not an issue in the vacuum of space?

My understanding is that the attenuation at distance is a function of geometry: https://en.wikipedia.org/wiki/Inverse-square_law

Yep. It's why pretty much every force follows the inverse square law, whether it's RF signal strength, sound volume, electromagnetic attraction or gravity.

Sort of, the strong and weak nuclear forces don't.
