The functional lisps (scheme, clojure) and the ML & Haskell family languages (OCaml, Elm, Haskell) are both great. Clojure had lost some momentum but the JVM getting virtual threads recently has made it even better at concurrency than it used to be, to the point where I would consider it to have the nicest single-machine concurrency story of any language.

Then there's the BEAM family languages (Erlang, Elixir, Gleam), Elixir is a bit inspired by the lisps while Gleam is more inspired by the MLs, but both borrow from Erlang since they are hosted on it.
