Another thing to consider is “follow the money”. I’d expect all the book-recommending youtubers with high throughput to have some sort of affiliation with a publisher or somesuch…
Oh yes I learned about that recently as well 
OMG hard pass 
Yes. Or rather “cringe me to tears” in my case.
Luckily at times there have been really good books among the winners (and the follow-up list) as you can see in The Honya Taishou 本屋大賞 Reading Challenge, but unfortunately it’s not a given and one has to be careful. It’s a prize for popular books, after all, which doesn’t necessarily mean good books.
