I second the suggestion of Chopin Preludes, there are many within your reach you could choose from. There are also some nocturnes, such as the first ones from Op. 9, Op 15 no 3, perhaps Op. 27 no 2, Op 37 no 1, Op 55 no 1, Op 72 no1.
Debussy has some preludes in book 1 you could handle. Also Clair de Lune, Arabesque no 1.
