I'm looking for a classical piece of music to sing?

I am a first soprano with a four octave range, and I prefer to sing classical music such as art songs and operas. Do you have suggestions as to any foreign songs I can perform for my choir final? I would like to do something a bit less mainstream than Caro Mio Ben or Sebben Crudele. I am also singing the songs "Wishing You Were Somehow Here Again" from Phantom of the Opera and "La Fontaine" by Connie Dover. Any help would be much appreciated.
