Good songs for a solo and ensemble choral competition?

I am a Soprano 1 voice part. High range but can sing down to soprano 2 range. I am a 16 year old girl. The solo must be a fairly clical piece in any language (english, Italian, or french would be best). It can be any length. I have a "boy soprano"voice (pure tones not as womanish although I have woman vowels). Please give the song and composer and if possible include a link to the piece or a video of someone singing it. Thank you!
