I know there was a UE5 EA document that detailed the nodes at that time, but I’ve lost the link and will look for it. It lacked currency anyway.
What is of use is this kb article that describes the changes since EA. This has some very valuable stuff in it:

I agree on videos, very difficult to learn that way.
The Epic Audio Dev team has been outstanding in helping out with individual questions here in the forums, so I agree with @SteveLane, posting the question here does bring Metasounds insight that documentation might not even cover (though there is no replacement for API docs with snippets).
