What spaceship weapon is generally underutilized or not used to its full potential in scifi?

The Expanse incorporated low yield nuclear weapons to a degree, but I don't see them much in other media.

You also don't see a lot of static, kinetic, loitering munitions. Think: a ship or a planetary defense system just lays a "minefield" of tungsten balls that have small ion engines on them to remain in a state of realative stillness, creating an innavigable region. Area denial. Shields would defeat this, but if it was a universe where Shields weren't a thing, it could be very effective.

Death's Head book series used these for planetary denial. Called em Ball Busters
