I'd search for material from Scott. Some resources that look promising:

- F# in Production with Scott Wlaschin: https://shows.acast.com/664fde3eda02bb0012bad909/664fde448c7...

- https://fsharpforfunandprofit.com/posts/completeness-intro

I don't have any major prod experience with F#, but it seems F# is as mature as .NET itself (at least there is full interop with C#.)

Also don't forget functional languages make it more convenient to apply functional thinking, but with discipline you can implement functional thinking in pretty much any lang.
