I know it's already been mentioned, but I just wanted to endorse https://fsharpforfunandprofit.com/ again - you could not ask for a better teacher than Scott Wlaschin if you want to learn F#.
It's a great resource for F#. If you also want to get really strong in functional programming fundamentals I highly recommend taking Prof. Dan Grossman's free online course https://www.coursera.org/learn/programming-languages/ --he's a great teacher and the subject matter is great for all levels of experience.
