Depends on what you really want.

Erlang, in my experience, is not a functional language at all. There is a thin veneer of functionality, true, but mostly it's an object-oriented language, Smalltalk-style. They say "process" instead of "object", but it's basically the same thing.

If you want a language that is significantly more functional (although still not really), and also quite practical and popular in the industry, you can try Scala. Especially Scala 3, which seems to have fixed quite a lot of grievances, in particular those related to Odersky not really understanding math. Additionally, in Scala world you have Akka, which is modelled after Erlang's multithreading model, so you don't really lose anything important.
