I just performed the Beethoven op. 1, no 3 -- it is transparent and virtuosic. Don't think for a moment it will be easy. You will have to work hard to play it well. I personally would recommend looking at the following (in reverse chronologic order of composition):
Miniatures by Frank Bridge (four collections of three works) - late Romantic, British
Four Short Works for Piano Trio by Paul Juon - late Romantic, Russian
Debussy's Piano Trio (written when he was 19, not a mature work, but a good piece even if it is a bit derivative)
Faure "Apres Une Reve" - arranged for piano trio by Akira Eguchi. Beautiful, very playable.
Although they are long and have difficult sections, either of Schubert's Trios Op. 99 or Op. 100 are very playable and quite lovely.
Any of the Mozart Trios - while the cello parts are not as independent as in Beethoven or Brahms, they are still pure Mozart. Every note is perfection. My favorite is the E Major.
Any of the Haydn Trios - the cello line usually doubles with the piano bass, but this is not a bad thing. Charles Rosen devoted an entire chapter in his book, The Classical Style, to these works. They are under-played and beautiful.
I personally think the piano trio is the ultimate in chamber music. Small enough to make organization and rehearsals doable, large enough to thrill audiences and fill halls. Today we read through the Schubert 99 and the Brahms C Major.
