Nords, Imperials, Dunmer, and Bretons all have a fair selection of both sixes. There are only 2 Redguard females (1 requiring DLC), 2 Altmer females, 1 Argonian female and 2 Argonian males available, and no available Redguard or Altmer males, or Khajiit or Bosmer of either six. (On edit: I forgot--there are 2 marriageable Orcs of each six.)
If you have a PC, you can use console commands to make some NPCs available for marriage who ordinarily wouldn't be, but they have to have the dialogue available. In other words, if they have a unique voice actor, it's not going to work; they have to use a voice actor who has recorded the appropriate lines. I don't know the commands myself, but I'm sure someone who does will weigh in!
Faendal can be added this way; his voice actor is Jon Curry, who voices several marriageable NPCs. I don't know whether there are any female Bosmer who can be added this way: Brelas is the only single Bosmer female I can think of off the top of my head, and I don't know who voices her.
