I think I would go with
Cara as a nn for
Caroline. Maybe
Careen,
Carine, or
Carys.
My sister's middle name is
Carrie (after our great-grandmother who was born in 1901). Neither of us have ever liked it very much. One, because it is a little dated, but also because it's basically the word "carry", so it's like there's an implication of carrying a burden...and then there's the movie/Stephen
King novel.
I like
Callie (it makes me think of calla lilies), but it doesn't sound like a natural shortening of
Caroline to me.
