Lighting assignment setup

I teach a lighting class for CGI/VFX students. As part of their assignment I get them to light a scene that I've set up the background and characters for, so that they only need focus on the lighting. This year the scene is made up of the Jerry rig and some Quixel Megascan assets.
I'm particularly interested in getting the students to consider contrast ratios this year and to learn but then potentially move away from 3 point lighting.
