Could you recommend Mozart piano pieces?

I intend to learn a piano piece by Mozart (or maybe Beethoven). I have
been looking for some "middle level" pieces, but I'd like you to
recommend me some that you think is best.
To give you an idea of the level I'd expect, I play quite decently (I
can improve on dynamics and articulations, though):

Rondo in D major, K.485 (Mozart)
Fantasy in D minor, K.397 (Mozart)
Third movement of Piano Sonata No.8 in C minor "Pathetique"
(Beethoven)
Nocturne in C# minor, Op. Posthumous (Chopin)

Oh, and it's better if it is a fast piece (I mean like Allegro better
than Adagio).

Thank you in advance!
