I’m also pretty sure you cannot apply for an AOS from a B1/B2 to a green card.

I think you can apply for an AOS to a different dual intent visa which could then allow you to apply for a green card if you meet the requirements for that visa.

Maybe something like if you get married while visiting, but even then I believe you need to apply for an adjustment of status to a marriage visa and then apply for a green card.

No. Before you could enter on a tourist visa and there was an automatic presumption of fraud if you got married, etc within the first 90 days, but you could get married after 90 days, but before 6 months of maximum tourist stay and they may investigate a little bit, but it was generally not difficult.

The IR-1/CR-1 that you describe is how a spouse would apply from outside the country.
