I have no idea if it is good for anyone else, but I've had a lot of luck using "build your own wiki" tools, and specifically Obsidian. I feel like when I'm learning about a subject I'm not super familiar with, it can feel like "drinking from a fire-hose". There's a million different proper nouns that you have to learn, and each one can be a rabbit hole in itself. I feel like with Obsidian/Roam/Logseq/Athens, it helps me focus on the high-level and drill down on tasks as I grow more familiar with the subject. It also creates, in my opinion, extremely easy-to-read notes later, more or less like I'm just reading through Wikipedia. I don't think it's for everyone, I couldn't get my wife using it, but I genuinely do believe it has helped my knowledge-gathering a lot. ------ In regards to your second question, if you had asked me three years ago, I would have said videos, but honestly as I've gotten older, I don't think I have enough patience for them anymore, and generally prefer books for conceptual stuff, and articles for practical stuff. Videos are often way too slow, and I end up having to listen to it at 2x speed anyway. The exception to that is if I'm trying to learn something somewhat interactive (e.g. how to use Blender or something).
