I really dig the NYC CNC channel. (Also Clickspring and This Old Tony, but that's beside the point
That said, I try not to look TOO close at Fusion or any other application. Nor do I try to emulate them directly. They're different applications with a different audience, history, tool kit, etc. There's certainly something to learn from them, but that isn't necessarily the right
way to do things or the right way for us
Two other things that I've gotten a lot of value from are:
1) Building stuff. There's nothing like the taste of your own dogfood to find the problems.
2) Teach a class. This is a hugely humbling and amazingly productive way to see what works and what doesn't. Anybody who teaches a class and summarizes the experience has my undivided attention. If you can't teach a class, make a video. It's the same kind of experience. If it isn't easy to explain in a video, it probably isn't easy to learn.
