They make good Bards, obviously, but also good Sorcerers, Wizards, Rogues, Rangers, and perhaps even Paladins (A lightly armored Paladin, but a Paladin none the less). Not that any other class is bad, but those are clases that they have strengths that they play well too. Being fairly inquisitive, a class that allows them to explore or experiment with things is a good fit (Like most of those mentioned), and given their facination with other cultures, there's no reason they couldn't worship just about any god as a cleric or in general.
Just don't take Exotic Weapon (Katara), as that would be frowned uppon
