Any pine or cedar (or other conifer) is highly resinous and will coat the inside chimney which creates the potential for flash fires.
Any of the fruitwoods are considered to be classified as a hardwood which burns cleaner and has little residue.
Even though my mountain home is within a pine forest, I burn Eucalyptus and Orange wood. The euc is by far the hottest BTU rated burning wood, it's low in residuals, is clean and has a great smell. Orange and any other citrus is similar.
Resinous woods will coat the inside of your fireplace chimney and someday it could ignite and you'd have a giant roman candle...which may even blow into the room as well as upwards. Witnessed this once and its some scary stuff.
Someday, have your fireplace flue cleaned by a professional Chimney Sweep...well worth it as precautionary insurance and piece of mind.
