I was tested 2 weeks ago for antibodies after receiving the vaccine. My results were "0." And yet I experienced all the typical side effects from the vaccine, indicating that I probably had an immune response to it.

Nobody knows what any particular antibody count means with respect to risk to your health from a future COVID infection. Instead, we need to be looking at the hard statistics about who's getting admitted into hospitals and who's dying.

Genuine question: Do we have data on hospitalization and mortality rates of unvaccinated but previously exposed?

The data I've seen is not great, in part because reinfection is pretty rare. This study [0] indicating rates of 31.0% and 3.4% respectively is the best I've seen, but I'd hazard a guess that there's some sampling bias - i.e., healthier people are less likely to get symptomatic reinfection and therefore to get tested, so unhealthy people are overrepresented in the data - so those rates are probably overestimates.
