Solo repertoire?
There's plenty of baroque and classical music out there for the transverse flute that can be played on the recorder. I like to play G.P. Telemann's Fantasias, and J.S. Bach's Partita in A Minor for solo flute.
You might look into getting yourself a large book of "popular classics" that includes well-known romantic and classical themes from things like Swan Lake, Symphony of the New World, Peer Gynt, and the like. If it's written for piano, and you have a partner or two, you can easily arrange it to your taste.
If you've never heard of Michael Praetorius, you should acquire a collection or two of his music. A Renaissance master. He wrote many lively and short dances, but also many beautiful religious pieces.
I'll see if I can't give some more suggestions later. Do you have preferences of style, period, arrangement?
