As someone who quite likes f#: It seems like a chicken and egg problem, not many companies doing f# because not many devs know it and not many devs learning it because not many companies are doing it.
I certainly wish I were doing f# professionally, but I only ever found 1 job listing for it, and that was in vienna while I am located like 200km away from it :(
Speaking of elm: I really like elmish for the frontend, when I need to make a dynamic page in the first place. Maybe that could be to your interest? (It transpiles to react under the hood via fable, which you can webpack into a drop in bundle. But I digress)
