I would add F# to that list, which is an ML language as well.

It works on almost any platform, be it web, mobile, desktop or server via Fable, Xamarin or .NET Core.

It can work as an object-oriented language as well, which makes it easier to interface with C# code, but the documentation makes it very clear that functional is the way to go for F#.

For UIs there are libraries like Fabulous and Elmish, that provide a very similar programming model as Elm does.

You can even share code between all your target platforms:
