I’m not sure the tools have evolved that far.
Have a look at this recent video.
Episode 6 rigging
You could create the above rig that affects a single bone. Add that control rig to a BP and attach a cine cam to the bone socket of the Control rig.
Your suggestion of adding the CR to the sequencer and then parenting a cam is also a good one but that’s the kind of fragmented workflow we’re both trying to avoid adopting.
CR is still evolving so hopefully the BP & timeline integration will get better citizenship over time.
