Modern air to air missiles (AIMs) might be a good place to start. They would be equivelent to what a merchanter might be able to afford. Pourpose built warships would of course use heavier and deadlier missiles, compairable to air to ground missiles(AGMs), or even torpedoes.
AIMs have a 30 to 50 G thrust, depending on type and model. They carry warheads in the 9 to 50 Kg range. The thrust phase will last only a few seconds, after that, they coast to the target. The warheads are not designed to kill by impact, but by near miss. A target detector will trigger the warhead when the missile is passing the target. The warheads are designed to throw frag in a band perpendicular to the missile flight path. A direct hit is overkill
AGMs have less peak thrust, but longer susstained powered flight phase. The warheads are usually heavier, up to 100 Kg.
Anti ship missiles will have a much longer thrust phase, and lower max thrust. They mount much heavier warheads, up to 945 lbs NEW.
Torpedoes, I have no direct experience with, but would be what a Imp heavy cruiser might be expected to use against a Zho cruiser to rip it open.
I have seen many new missiles come on line, replacing older mods. Improvements include increased max thrust, improved guidance, better target detectors, ECCM electronics, and tighter turn radius. I have not seen improvements in warheads for many years.
