I heard that JKs Cities can cause performance issues on lower end PCs and as alternative I found the Dawn of Series (Dawn of Whiterun, Dawn of Windhelm and so on, there's probably a collection on nexus). I can't run it on my current plopsty pc but the mod reviews I saw seemed very good and optically I like it better than JK.
Another nice one is Towns and villages enhanced, takes care of the smaller settlements adding buildings, deco etc.
When I was browsing nexus yesterday I think I saw exactly what you wanted for the DB. If I recall correctly, there was one mod enhancing the dawnstar sanctuary plus adding a few members, and another one just adding about six members. I'm on mobile now so no links but try browsing the guilds/factions category on nexus, it's pretty small but you'll find what you are looking for.
To improve role playing, alternate start - live another life is a must have in my eyes.
I also like the immersive patrols mod, it adds some well needed life to the landscapes of our beloved skyrim.
I have been looking into mods for weeks now, I watched the plops out of Broduals channel, so if you specify some more on your wishes I might have plenty more ideas.
Oh, also look into GEMS - gameplay enhancement mods for skyrim. They have a Website listing mods in categories like immersion etc, and they selected very nicely according to how the mods fit into the game.
