Probably nothing helpful as you are already way past my understanding. Maybe look at the Darktable documentation or even the “green lantern” stuff (IIRC the name). GL or (something) Lantern is/was an open source software for Canon cameras that breaks out all DSLR features on nearly any Canon camera.
Nearly a decade ago, I had a makeshift product photography studio and messed with Macbeth color charts and profiles matched to a monitor. The tutorial guides I followed were from these two projects IIRC. GL.
