I run a homelab and have no trouble finding enthusiasts who go super in-depth about how to use the hardware and software. Where are the good Apple ecosystem enthusiasts?

So as the title says, I run a homelab with various technologies — Proxmox, Home Assistant, a reverse proxy, lots of Ubiquiti equipment, and so on. Over the years I’ve consumed countless hours of articles, stack overflow posts, youtube channels, and knowledge bases to keep myself up to speed on how to use this equipment and what new outcomes I should aim for.

I’m also deeply invested in the Apple ecosystem, with Apple TVs, iPads, Phones, Macbook Pros, and even a homepod. I’ve noticed that the Apple equipment has far less documentation on the whole. I watch Apple events to learn what new features a device will have, but I don’t really see a lot of tutorials or even instruction on how to use it.

Where do you go to get the kind of in-depth learning for your Apple devices that is needed to make expert use of them? Do you have favorite youtube channels that I haven’t discovered yet? Please post below and let me know!
