so what goes: rattle rattle clink clink clink ?

No rattle or clink, it is almost like a shopping cart oscillating,
but faster cadence. The wheel has no play installed on
fork,(bearings)spin smoothly on/off bike. Happens while freewheeling
or pedaling. Happens after hitting a bump and only happens at higher
speed, 20 plus. Seems to have some drag, when happening, not
confident inspiring. Very strange.

Does it have bladed spokes?

I wonder if they are somehow vibrating with the air passing over them
after a bump sets off the oscillations?

It might be that the spokes just need to be tightened to increase the
resonant frequency?

Perhaps get a bike shop with wheel building tools to check the spoke
tension is something like 100kgf
