They're the only ones, really.
Hmm, anything else will have some small kind of voltage effect due to simple mechanical stresses and electrostriction. Mostly very small, ppm range.
Electrolytics can, over a very long time scale where, at lower voltages, the oxide degrades and thins, so C goes up; and when maintained at nominal voltage, or reformed back to it, C goes back down (or down further if over-formed?).
Self-healing films will drop over time, but that's a persistent effect, and only after overvoltage.
Varactors obviously do, but arguably aren't capacitors, because they're diodes. They're also explicitly made and sold for that purpose.
