Which answers the original question. Those races are popular amongst people with that cultural background because they are significant to people with that cultural background. There is nothing mysterious going on.
I've never said otherwise.

Mythology and local stories.
Meanwhile many Tolkien fans seem to question the universality of ak animal person ignoring the fact that almost everyone knows for example what a cat acts like and could thus easily extrapolate that to a cat person.
This thread sure has been a wild ride. The answer that that the appeal of elves and dwarves is a nostalgic desire to recreate the lord of the rings, is in retrospect so obvious as to make me wonder why I ever asked the question, yet so many of these comments are baffling counterintuitive.
It would seem obvious to me that "I'm a dwarf like that book with dwarves" requires far less creativity and role playing than another more interesting race yet their defenders seem to have the opposite idea.

Such as? When we are talking about tropes, local stories (meaning what, a city? A province? What is local?) we are talking about things which transcend personal experience and are more generally known to provide a framework of general understanding.
I would say it's more than just Tolkien. An entire generation of novelists and game designers were influenced by Tolkien and D&D. Which leads to a feedback loop.
Cats are the exception to the general rule but even then you only have minimal behavioral characteristics, but what would their culture look like? Where's the widespread, easily recognized artwork depicting where anthropomorphic cat people live? For that matter, where do they live? Different people will come up with different answers which is not wrong, but not as appealing to some people.
They just lack a Tolkien to alter and popularize them.
Elves and dwarves aren't special other than that.
Dwarves in myth were grumpy greedy crafters on a dark rock-world.Right, so for the majority (I would imagine) they are not really 'tropes' in the sense of Elves = Live Long, Graceful, Magical and Dwarves = Short, Mountains, Miners, Treasure, Gruff.
