Shouldn’t we be distinguishing between unvaxxed who had Covid, and unvaxxed who didn’t?

None of those old studies apply now that omicron is around. Omicron spread all throughout the world at record breaking pace via vaccinated people, so it doesn't seem like vaccines are doing much at all to prevent spread of omicron.

You may be correct, but it's too early to tell.
As I have stated elsewhere in this thread, the rate of vaccine escape has gone up by about 5x, (from 6% to 30%), but that's still much better than one would get from no vaccination.

But it spreads so fast that it doesn't seem like that matters. It spreads basically as fast as people are interacting, if it gets into the student body then everyone will be infected in a matter of days even if they are all vaccinated.
I can't see how it could spread any faster than it already does through vaccinated people. A few people there being unvaccinated wont make a difference.

This is the big one. Conditional on symptoms the viral load may be similar betwee vax/no vax, but if the vax have much less probability of getting symptoms then all is good.
And that's after fewer people who are vaccinated catch the virus, and there's more aborted infections and asymptomatic infections after vaccination.
All of those studies use PCR Ct values as proxies for viruses and compare vaccinated and unvaccinated individuals with similar symptom severity, and it turns out that correlates at peak because symptoms are on average due to antigen loading. Those studies aren't very good at showing how effective vaccination is at preventing transmission. They just show that its nonzero.
