This is probably the best course of action, plus, you can always search for topics from the textbook, and presumably find the most useful sources for your needs organically.
In my personal exp as a late-twenties self-learner: finding high-quality sources of information is simple, identifying best relevance and staying focused is not. Perfectionism over resources is a total disaster for productivity. (And very mediocre, very shiny resources are easy and mildly profitable to create, and are often more for the authors' benefit than for the public good.)
Good heuristics are a savior - search for talks from authors of textbooks and langs, subscribe to those high-quality conferences (I like PapersWeLove), mentally blacklist channels judiciously.
