Just because you bacame the champion for the Daedra doesn't, at least not to me, mean that you are promised to each of their realms. The only one that comes to immediate mind that you serve in death is if you become a Nightengale. Perhaps as a member of the Dark Brotherhood Sithis would want to claim you, but Sithis is a whole new story as he isn't Aedra or Daedra. As for the main quest, you were extended the invitation, not the requirement, of going to Sovngarde. If you die a werewolf you're apparently promised to the Hunting Grounds, but that's a slightly different story as it is only mentioned as a definite in the Companions if you do not cure yourself of lycanthropy before you die.

If there are definites mentioned amongst the other Daedra I have missed them, and if it's there please let me know. This is all just from my immediate memory.
