Not sure how helpful this is for folks whose media experiences are very different from mine, but I’ve had absolutely no trouble finding things that I want to read. I have the opposite problem, actually 
.
If you’re interested in manga, the Bookwalker freebies thread is a great place to find stuff that might be of interest, and since it’s free, you can easily drop a series if it turns out not to be to your taste.
Other than that, I’ve also had some success searching in Japanese for recommendations. When I discovered the 大人絵本 medium, I searched the phrase in Japanese and then skimmed reviews (in Japanese) and chose a few books that looked interesting. The better your Japanese, the more luck you’ll have fine-tuning your searches and asking for more specific stuff, probably.
I also recommend following Japanese fans and/or content creators who are into your favorite genres on twitter. Most of my personal to-read list has come from following people in the Japanese pro wrestling community. I’ve seen wrestler autobiographies that I want to read, magazine interviews on topics related to wrestling and not, manga recommendations that look interesting, even a 大人絵本, haha. It’s the same way I find out about many cool books and such in English. If you find people that share your personal tastes, you’ll get loads of great recommendations that are much more likely to be books that you’ll enjoy.
