Baron, Baronet, Knight, Patrician, Esquire. Junker, maybe.
If you think in terms of how you acquired the nobility, you'll be better off for determining what the title would be (With Count being a limit, of course). For instance, was it hereditary? Does the noble possess or look-over land holdings? Was it an honorary or awarded title? Consider also that there are other esteemed roles that circle around nobility-- such as councilmen, courtiers, stewards, squires, chancellors, seneschal, and heralds.
If you're worried about taking a noble position due to the size and 'rank' cap in Barovia, you might enjoy considering the honorary, courtly positions too.
