I think playing through the Alfred Standard Piano Classics book is a good idea. Some of the pieces in there may be below your level, but it has Bach inventions of varying difficulty, a few Schubert waltzes, some approachable Chopin pieces (including the E-Flat Nocturne), Debussy’s First Arabesque, and even Mozart’s Sonata No. 5 in G-major. Plenty of other good stuff in there too and it helped elevate my playing immensely. I think you’ll find that the pieces cover a wide range techniques that are important for a late-intermediate/early-advanced pianist to focus on.

Thank you! I'll keep that in mind. I'm going to work on Chopin's Prelude in E minor later today. I also found a book by Alfred's Publishing, The Complete Book of Scales https://www.amazon.com/gp/product/0739003682/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
