I tried increasing the rebound in front, but it didn't seem to eliminate the occasional bobbing. I think it made the oscillations smaller in amplitude and maybe less frequent, but they were still there.

I did order some helpers and divider spacers to be able to lower the front a bit more, along with spring isolators for all 4 corners. The rear springs are 7 inches long and have plenty of room to lower before they'd not remain captive at full droop.

I thought the bobbing might be because of some binding at the caster pivot point on the front LCA. But if this is common behavior in these kinds of shocks, I'm not too concerned about it. It doesn't happen that often, although it's sometimes funny when it occurs at night. I kind of feel like an LA lowrider, when I see my headlights bobbing up and down off the car in front.

Thanks!
Good job on the helpers. Dunno why some companies don't include them on single height adjustable coilovers.

I'd at least try reducing the damping and see how it feels. A dyno would really help diagnose that, but it can just be one of the tradeoffs for one of these types of dampers. Some handle it better/differently than others but overall it sounds like you're in good shape.
