i think that a dragonborn who has done all sidequests will probably go to nocturnal's realm, as she's the only one they have actively sworn an allegiance to (they never say that they'll spend their afterlife in Herma-Mora's realm, and sithis doesn't count because the dark brotherhood is being tricked by Mephala).
