Adding a little more: I don’t think missiles will be used much except in very specific situations.
Stealth in space is not an easy thing, and you can generally “see” quite a long way. A missile will stick out like a sore thumb, and anything that mounts any basic defensive armament (simple railguns, coil guns, or lasers would work her) will make massed missile attacks economically ineffective. Too much will be expended with the missiles for not enough damage.
The weapons of choice will likely be railguns, coil guns, lasers, and possibly nukes fired as ballistic projectiles (harder to detect and intercept with active defenses).
As mentioned before, I think instead of fighters, carriers, and battleships as we see on TV, you’re more likely to see carrier-like ships tending hordes of disposable combat drones.
That’s pretty much what I think to, barring any kind of far-out space drive stuff. If we ever get really, really thin and strong nanofilament you could deploy that in nets tens of thousands of miles across as a defense or accelerate them to very high speed for drone sweeping weapons.
