I have a different perspective, they are gods or goddesses. Of course I am also a polytheist IRL. To answer your question you need to define what makes a god or goddess?
For instance in hellenismos(greek Polytheism) there are Nymphs which are spirits of local natural features. Many of them are just for local regions, ie mountains or rivers. Yet these local nature spirits are not anywhere near as powerful as the more famous olympians. That does not mean that they are not divine, and thus to me anyways if I am in a place that they are a part of then i make sure to also honor them in my offerings, prayers and activities.
I bring this up because the elven faith has always seemed more like polytheistic deities then others. If the elven gods were powerful mages, with unique magic. What prevents them from being consdered gods or goddesses?
P.S: why do you not talk about the Avvar Gods and goddesses
