Ask HN: Resources for Best Practice Haskell

My problem with learning Haskell has been that the resources are always very basic and beginner focused, or focused on learning category theory.

I'm from a STEM background and already know category theory, and I already know the basic syntax of Haskell - where can I go to see what the people proficient at the language are doing?

I mainly program in C++, and there are literally tonnes of advanced projects to find on github using well-written C++ to get into, not to mention all the videos, podcasts, discord communities and books on C++ best practices.

The best option I've found for Haskell so far has been to look at the standard library implementation for different functions, but what else can I use/do you use for learning intermediate/advanced Haskell?
