What Classic literature should I read?

I'm looking for suggestions on classics that I should read – I just finished East of Eden (phenomenal) and am currently reading Wuthering Heights (so far it's pretty good). I've read a lot of fantasy/scifi but I'm currently more interested in books than have stood the test of time/had a significant cultural impact.

Below is a list of all the classics I can currently remember that I've read, in approximate order of how much I liked them (not sure if Midnight's Children is a classic but it is probably my favourite book of all time). I'm not a huge fan of Jane Austen or Dickens, and I'd rather read new authors but am open to repeats.

Ideally looking for novels that aren't too much of a slog in terms of length (looking at you Russian classics/Count of Monte Cristo), but I'm open to all suggestions, especially books/authors that I might not be familiar with!

Midnight's Children, Stoner, East of Eden, Brave New World, LOTR/The Hobbit, Kim, Slaughterhouse 5, Catcher in the Rye, 1984, 20,000 Leagues Under the Sea, The Great Gatsby, The Picture of Dorian Gray, Animal Farm, Crime and Punishment, Of Mice and Men, Portrait of the Artist as a Young Man, The Brothers Karamazov, The Stranger, The Time Machine, On the Road, Around the World in 80 Days, The Bell Jar, The Odyssey, Great Expectations, The Trial, Robinson Crusoe, Pride and Prejudice
