The book "The Paradox of Choice" led me to using Wirecutter and Consumer Reports in recent years - if it's not something I care that much about, I will just buy whatever their top recommendation is without second thought. The cost of the subscriptions pays for a human to wade through all the junk and select something that is at least adequate for the job, and is cheap compared to the effective hourly rate of having to search through mountains of junk.

For more niche stuff, Reddit groups like BIFL and seeing what niche hobby groups coalesce around is helpful for me. Which I suppose is the same reversion to word-of-mouth expertise when, as you said, brand and price are degraded signals.
