Avra is sweet and simple and unique. I like it. Would you say AYV-ra or AVV-ra? I think I like AVV-ra better.
Ara is okay, but it does feel a little incomplete to me. It could easily be a nickname for something like
Aria,
Ariadne,
Ariella,
Ariana,
Araceli,
Araminta, or
Arcadia if you're not a fan of
Arabella.
