Gravity doesn't cancel like the electromagnetic force, despite otherwise decreasing at the same rate.
I've never heard an explanation of the strong or weak forces that I actually "get" enough to understand their distance effects.

I thought this was excellent (in all ways) but particularly for your question: https://www.youtube.com/watch?v=UYW1lKNVI90
Edit: so for weak, I think I understand that "photons are massless, so are only subject to the inverse-square law; weak bosons have mass, so are also subject to decay". But that doesn't explain to this dummy how the strong force works, since gluons are also massless (... though mesons are not? but they're not fundamental).
