I'm not sure if this constitutes what you're looking for, but you could add temples. The player could purchase religious artifacts (amulets of the Divines, books, blessed clothes or armor, etc.) and receive a blessing from each of the Nine Divines. Other than that, how about a place for fighters to gather and revel in their accomplishments? It would be like a more relaxed version of the Companions, perhaps with an odd job or two. In fact, you could make it a place for veteran Companions. Drinks, pelts, weapons, armor, and whatever else could be sold there. Those are the only ideas I have at the moment as your list is already quite extensive. Good luck, I hope this helped.
