All the vampire types can manage this, actually.
White court obviously (though they do start going all silver-eyed if they go too far into demon-mode).
Red court, until they take consequences and start losing the flesh mask.
Black court, if recently turned or skilled enough to put up a veil.
The fomori might count - they look at least mostly human anyway. But they might count as fae; depends on what definition you're using. On the other hand, they do supposedly sell their work to others, so altered-formerly-human fomori servitors could show up working for just about anybody.
We know that Tengu exist in-setting, and they traditionally have the ability to appear human. Though we don't really have any more in-setting information than "tengu exist", so...
There's also evidence for some specialized human spellcasters being able to use physical enhancement magics to dramatically increase speed (and possibly other attributes as well), without actually shapeshifting.
Oh, and there are a couple of denarians that tend to look human rather than going all freaky-battle-form.
Zombies.
Rakshasa - we know they exist, but don't know what the DFRPG rakshasa actually looks like. Probably fairly powerful, though, unless they're a race with gradations from prince down to foot soldier.
That's all I can think of for stuff we've seen in the books.
I could easily see specialized golems that look at least mostly human.
And, hm, what was that lovecraft thing... "worm that walks" or something like that? Some sort of roughly human-shaped colony of writhing things; requires heavily concealing clothing including gloves and a mask to appear human, though.
Some interpretations of kitsune could work.
