The internet and books primarily focus on beginner-to-intermediate process, so there's very little resources beyond that. I've found ChatGPT to be exceptional for explaining things beyond it, like getting into more advanced Rust topics lately.

I think the key is to treat it like an experienced mentor that can make mistakes because of imperfect memory, not a perfect talking encyclopedia. Web searches don't always have the right answer, and even experts with decades of experience (cough) still get things wrong regularly. It's a collaborative conversation.
