How do you find good information and advice for subjective topics?

I'll fully admit, I'm not the best at research, but every time I try and get information such as "what headphones should I get" or "what's the best way to meditate as a beginner", it's about 99% either ads or AI written articles that's basically a glorified sponsorship. How do I find information like this (for anything, not just these examples) in the mountains of garbage that search results produce?
