Need a recommendation for a new piece

[boston9]

I am aged 64 and have been playing for 4.5 years. I am retired and I practice a lot. Have worked through the Mozart Piano Sonata #4 and can play it from memory albeit crudely, with inevitable mistakes, but with surprisingly sustained periods of real expressivity, particularly the first movement. While I continue to polish the piece I would like to tackle my next piece which would help me advance my technique and seriously challenge me but not crush me. Looking for something no more than 20-25 minutes and I wondered if a contrapuntal piece would be one to consider. But I am open to any period.
I play on a 1961 Wurlitzer spinet. My hands are not large and each can accommodate one octave only. I would really appreciate any suggestions. Thanks.

How about a handful of Soler sonatas ?

You can simply pick and choose to fill your time requirement

Thank you for your suggestion and the link.

Try some Stephen Heller. Perhaps also the early sonatas of Beethoven, no.7 in D is just about the easiest. Or some Haydn (perhaps the early sonatas in D or C Minor). Soler is fun.
