I have a few questions. Can it do GUIs well? How about mobile? And how does it compare to e.g. Scala?

It can do GUIs well, although it takes some finesse to manage user state in an immutable-first language. Check out Fable for building web apps: https://fable.io/

I don't have much experience with Scala, but I think the two languages are pretty comparable in their respective ecosystems. The biggest difference I'm aware of is that Scala has typeclasses and F# does not.

F# is not really that strong on immutability, though. Sure, variables and struct fields are immutable by default, but making them mutable is one keyword away. Similarly with classes - declaring readonly properties is more concise, but when you need a read/write one, it's readily available.
