Just my two cents - but a general purpose language is going to need to be coupled with design patterns in order to be useful for different tasks.

I'm using MVC design patterns for some codebases, I'm using DDD plus Event sourcing and Event Driven for others.

I suspect that you are thinking of a small subset of design patterns (eg. Gang of Four derived patterns like Visitor, Strategy, or Iterator )

All examples of OO nonsense. There is only one pattern you need (functions) (tongue-in-cheek): https://fsharpforfunandprofit.com/fppatterns/

Edit: Also consider using the ELM architecture instead of MVC: https://guide.elm-lang.org/architecture/
