I think if you are worried about vibration and drag, Son, SP, and one of the better Shimanos are your only choices. I find that it's hard to true a wheel with the low-end hubs because the drag is so high. Might not be the same at speed, but it's annoying in the truing stand.
There is a resonant system formed by the hub windings, the light electronics, and the fork and tire. I used to have a home built circuit 7 pilom light that had obvious resonance at a different speed than my Luxos or Supernova lights. It really depends on all of the elements. I don't think you are going to get away from it unless you are using a highly-damped carbon fork
