Liszt - S. 139 no. 1 "Preludio"
The first (and easiest) of Liszt's Transcendental Études, which is mostly arpeggios with a few trills thrown in. About a minute long.
Liszt - S. 141 no. 4 "Arpeggio"
Liszt's 3rd version of a piano transcription of Paganini's 1st Caprice; also the easiest Étude he wrote, consisting almost entirely of arpeggios with a handful of runs in staccato thirds. About two-and-a-half minutes.
Debussy - Jardins sous la Pluie
One of Debussy's more famous Estampes, consisting mostly of arpeggios and trills. A bit more challenging than the above due to technical and musical demands, but I wouldn't call it too advanced.
Those are just a few that come to mind. Hope this helps!
