Positional chess books for breaking ~1900 fide?

I haven't played tournaments in a couple of years but I was 1800+ for a while. I feel like I'm better now, let's estimate around 1900+- fide.

I want to improve positionally, learn more advanced concepts and just understand the pieces and setups more. I'm aware of aagard's books but I've heard they're geared towards 2200+ players to improve whereas I'm trying to get there. Is this true?

I've also heard yusupov's books are good but I'm not sure which level they're aimed at. I understand all the basic principles like weaknesses, good/bad pieces, weak squares, doubled/isolated pawns etc. so I don't want to go through that again.

I just want some suggestions. Thanks.
