If your looking for mid-level classical : Bach- Prelude bwv1007, Chaccone bwv 1004, Gavotte en Rondeau or Francisco Terrega - Carprico Arabe. Although Carprico arabe might be considered upper mid-level, but you can learn quite a bit from studying it.

While it's not all "classical music":, Jose Feliciano has an entire catalog of classical, pop, Latin pop, and rock arranged for the nylon string guitar, everything from "Malaguena", to the Doors, "Light My fire". I'm sure there's something there you would enjoy tackling.

Here's his tab catalog on UG to get you started: https://www.ultimate-guitar.com/search.php?search_type=title&order=&value=Jose+Feliciano
