Hard to explore this vast Bentley Communities site, so can you point me to a CC forum, and to any introductory material that's comprehensible, not just marketing, and not assuming heavy-duty familiarity already?

Hi Tom, I can't help with most of your questions, but I can point you to the Reality Modeling community:
https://communities.bentley.com/products/3d_imaging_and_point_cloud_software/
Both Context Capture and Point Tools are covered, along with Acute 3D.
