A previous company I worked at was using mixed reality years ago (>4) to train manufacturing operators on manufacturing processes.

It ended up looking like a simulated workbench with low-detail models of CAD parts that needed to be assembled - it was pretty cool. Engineering companies are very ready for this technology.

A local school here trains nurses in a VR environment that is situated inside a fully built out wing of a hospital. The headsets come down from the ceiling, all the equipment is real, but there are dummies in the beds, and some observation screens for others who supervise.
