As far as genres, that would be a broad range. When something is written very well, I can often enjoy it even if the subject or story isn't of particular interest, and it it offers me information that I'm looking for, I can tolerate even stuff that isn't written well. This isn't true across the board, however. While I have enjoyed nearly everything that John Steinbeck wrote, I couldn't finish The Pearl even when it was an assigned reading, despite the fact that I suppose it was written well.
In elementary school, which went through 8th grade, when they handed out reading lists, there would be one or two books that were required reading, and then we could choose a specified number of other books from a long list, and I would usually read them all. On a report card from 3rd or 4th grade, the teacher had actually written, "Reads too much," but that might have been a reference to my reading a novel while she was trying to teach math.
I have also chosen book in spurts. For example, I read every John Steinbeck book I could get my hands on in 6th or 7th grade, and I would do that with other authors as well, and still do to some extent.
Alternatively, I might do something similar with topics. A couple of years ago, I devoured memoirs written by ordinary people about growing up in different parts of the country around the same time, or as much as a decade earlier, than me. Many of them were not particularly well written, as these were probably the only books an author had ever written, but I enjoyed the stories of what childhood was like for people in the South, out West, or in New England.
Then, I read novels that targeted the then growing Boy Scout movement in the early 1900s. To meet their interests at that time, there was a whole genre of novels for kids 11-18 or so, many of them written horribly, or with a formulaic structure similar to the Hardy Boys and Nancy Drew.
I have delved into memoirs and a few novels written by or about people who lived in Germany or the areas taken over by the Nazis in World War II, wanting to get a perspective of World War II from the other side. While there were some of what seemed to be genuine perspectives, there was a lot of virtue signaling. Of course, fervent Nazis in Germany were not generally permitted to publicly maintain that stance after World War II.
World War II and the U.S. Civil War were also topics that I delved into pretty heavily, while, for some reason, the American Revolution didn't hold the same interest, at least not to the same extent.
