Looking for acappella suggestions for a soprano

I'm a solo singer and can't play an instrument to accompany myself. And I'm tired of trying to find someone to play for me. So the only option is acappella.

I want to perform at open mics, but could use some repertoire ideas.

To narrow things down, I'm not a rock-type singer at all.

I like to sing folk (trying to stay away from all the obvious stuff), Irish and Scottish folk, etc. I can also like Broadway-style songs, but don't know much that would work without accompaniment.

If anyone wants to hear what I sound like, I could post my soundcloud page.

Thanks for any and all help!
