Besides the regular ones there could be
Mine-missles: hover silently or cruise slowly on preset course until they find a signature that meets their programing. Then they drive down upon it. Favored among frontier merchants as a way to leave a "present" behind them for pursueing corsairs.
ECM missles: An active ECM with a rocket propulsion, used to imitate a spacecraft. Widely used.
EMP missiles: shreds the targets computers with an electromagnetic pulse. Loved by pirates who desire that their prey not be destroyed. Paradoxically also liked by police for the same reason. Also used in trade wars when causeing to many casualties gets the Imperium's attention. Cannot cause damage to a military vessel but does great harm to a civilian one. Depending on the setting damage can be temporary or permanent.
Courier missiles: messages to another part of the fleet carried in a missile
Sensor missiles: fills a similar tactical niche to a sonobuoy in pre-starflight wet navies, but is self propelled.
Of these, arguably none except a EMP is a missile as normally thought, but all are self-propelled and use a similar mechanism.
