They are not humanoids they are called a BEAST race for a reason
I'm not aware of any of these things being called a beast race. If you're going to make claims like this, you should probably provide some evidence.
On the other hand
- Centaurs, you should probably stay away from, as they are monstrosities; and
- Dryads, you might be into, but they are fey and so not an option. Sorry.
And here are a bunch of things that actually are
beasts.
Also, fun fact: humans are animals!
Also, also: we are talking about an imaginary world - there are going to be lots of things that don't map neatly onto things that exist in this world.
