Chantell, if you are able to move plants outdoors during the warmer months, that will greatly increase your odds of bringing fragrant flowers to bloom. Just do it gradually as the plants will burn. Just growing indoors year round will limit you, for sure.
Oncidium Sharry Baby might be happy indoors ,it smells like chocolate.
The fancy big leaf phalaenopsis are lightly fragrant and would do well indoors.
Most of the large flowered cattleya are incredibly fragrant ( think hyacinths, roses, spicy) but really need a good amount of sun year round. When I lived in NC I ended up building a small greenhouse so that I could enjoy more flowers year round.
