Might also depend on how/where they died? Interference if they were soul trapped or otherwise got sent to one of the Daedric realms (due to vampirism or lycanthropy for example) seems plausible to me. And IIRC for Dunmer ancestral magic the big difference between that and standard necromancy is that the spirit isn’t coerced to come back; maybe most people aren’t interested in leaving their cozy afterlife after they die.

I thought about some of your points after posting the OP actually. I think I had forgotten the Summoner needs to have some kind of items or personal knowledge relating to the Soul that's being Summoned, like an Aetherial Phone Call, you need the Soul's number.
