Like I said, there isn't much more you can do for undead, I don't see how you can call wraiths and ghosts generic when there isn't anything else you can do with them. Goblins, yes typical thing in fantasy, I forgot about them but goblins are a well rounded creature. As for the generic wildlife? Really? Your really going to call animals that are from the real world generic? You know what, I think humans are generic, because we are animals and we exist in real life. OMG, TES uses generic races, because they are all humanoids and humanoids are generic because they exist in the real world. I can't believe someone really thinks that wildlife is generic and boring, that just shows you how out of touch some people are to nature...
Well, I'm sorry but I'm going to have to refer you to Morrowind.
More original undead: bonewalkers, corprus stalkers, bonelords, and ash zombies/slaves/ghouls. Each with their own unique lore, not just generic zombies.
And the real world wild-life was the rat.
Just because Cyrodiil is the capital province doesn't mean it needs to be more like earth.
