Avoid Brahms and Rachmaninov.
Try early Mozart and Ravel.
No no no! Don't do that - I can play Brahms with no problems. It's lovely and if you like the music, just play it.
As for Ravel - I found the Toccata from Le Tombeau de Couperin hellish for my span, but not impossible.
It think it's hard to say one composer writes better music for small hands than another. In the end, each person has a different shaped hand, different strengths and weakness with their own hand, and you have to work out for yourself how to deal with it. I mean, you don't see people with large hand spans avoiding pieces with chromatic scales and only limiting themselves to pieces with big chords, do you?
