Ask HN: What are the best Godot 4 production-grade learning resources?

I've been getting into game dev lately and chose to start with Godot 4, given all the recent events. I've spent quite a lot of time looking for quality learning resources, and most of them are on YouTube. The problem with that is that you don't really get a well structured path, and most of the times you don't really find stuff that's meant to be production ready.
