In a reading slump; need recommendations

Since the past two years I haven't been reading anywhere close to my usual reading rate. I don't really count my books, but I know that I've been reading much, much less than I used to. It's not for lack of trying; I'm just having a hard time liking any of the recommendations I get, both online and via my friends. I have a much easier time reading long fanfics, but even then, due to the uneven writing quality…it's kind of hit or miss.

Books that I've read and liked in the past:

The Count of Monte Cristo
Siddhartha by Hermann Hesse
anything by Terry Pratchett(mostly the Night Watch series)
Hitchhiker's Guide to the Galaxy by Douglas Adams
Northern Lights by Philip Pullman
Fire by Kristin Cashore
Song of Achilles by Madeleine Miller

What I'm looking for:
Books that are written well. Not having pretentious, purple prose, but not crude language either. Simple, pragmatic, use of language, poetic and raw writing also works, but I deeply dislike prose that is flowery for the sake of it. Writing that pulls you in, keeps you hooked, gets the job done.

Books that treat their characters with depth, and understanding. I want to read about characters that I care about, not flawless ice-cold queens or gross monsters with no redemptive qualities. The characters can be played straight(like Steve Rogers), complex and 3 dimensional(like Jaime Lannister), or nuanced(like Matt Murdock), but they must be treated with depth, empathy and understanding. For instance,…Sam Vimes is a pretty "black and white" character, but he still struggles with his addiction, with feeling like he doesn't deserve whatever good that is happening to him, deep down, and his fear of losing control and lashing out. He's a good man, a deeply good man, but he has layers. Similarly, Jaime Lannister is a good man who did objectively terrible things, and maybe became a bad person along the way, and his arc is about finding absolution, trying to get on the road to redemption, although it is still incomplete.

The point I'm trying to make is: I'm not looking for specific archetypes. I'm not looking to read a book just because it has a warrior prince as a character, or because it kills off a lot of major characters, or has gore and sex. I have no objection to those things, but I don't read a book because of those things. I read a book if I care about the characters. Because the story is about the characters.

One more thing: I don't mind heroes with noble lineage and everything, but I love to read about the every day men and women. The ones who don't plan marches and command armies, but the ones who draw water from the well and get drafted into the war when the time comes. The ordinary people, they may rise high or low, but their roots are among the ordinary people

Books that have a good sense of plot timing and execute it well-via pacing, elements of mystery, logical groundwork for events to draw upon.

Also:
I mostly read fiction. I haven't read a lot of non-fiction. if you have non fiction recommendations, please give those as well! In non-fiction, I'd like to read stuff that is interesting, engaging, written in a style that doesn't drag or plod, and has depth of thought(doesn't reduce everything to simplistic terms)
