Auth0's big feature that isn't provided by open source platforms at the moment is being able to request an OAuth token for third party services the user has authenticated with, so for example you can trade in an auth token that was issued when you logged in the user for a Facebook token.

Not true. Dex and Hydra both support it, although you need to implement a little bit more stuff when using Hydra. Read it in the docs: https://ory-am.gitbooks.io/hydra/content/connection.html

I stand corrected. In that case Auth0 is even more overpriced than I originally thought.
