Hi if you're still looking for suggestions, here are mine, based on you enjoying the Op9no2 in Eb, and saying the op15no2 in Fm is too difficult (darn double sharps, right? ;D).
Mozart K282 in Eb, mov1 Adagio
https://www.youtube.com/watch?v=quVhZA8cnQI A very sweet Adagio, not too difficult. Also there is a subtle playfulness, that develops in the second movement, and then bursts out in the 3rd. But it was really mov1 that sold me on this sonata.
Liszt Consolation no3
https://www.youtube.com/watch?v=MfDmUk7ie6s Deceptive, it is more difficult than it sounds. The harmonies are quite bold during the development, for example when it goes to E and Am, and I don't think most recordings do it justice (every seems to play the entire Consolation in ppp, with no dynamic range). So those can be fun to play with.
Chopin Nocturne in Bbm op9 no1
https://www.youtube.com/watch?v=ZtIW2r1EalM Perhaps a middle point, in terms of difficulty, between the op9no2 in Eb and the op15no2 in Fm.
Debussy Claire de Lune
https://www.youtube.com/watch?v=FoD_AxKoJDs Similar to the Consolation. The development is upfront about its difficulty, but the simplicity and sweetness of the first theme is what draws you in. Impressionist chords can be fun to explore.
