Without sterilizing immunity, will the amount of virus a vaccinated individual carries match that of a non vaccinated individual, though? I guess what I (a layman) is asking is, even if the vaccinated individual contracts the virus, won't they spread less of it than someone truly sick?

Someone truly sick is likely to isolate at home, due to the social stigma if nothing else. Someone who is asymptomatic may continue as normal, spreading the disease more easily.

It depends on the virus and the vaccine. We'll have to wait for further data on this vaccine candidate.
The Salk polio vaccine does not prevent infection in the digestive tract, so you can still spread the virus, but it does prevent the virus from spreading beyond the digestive tract and causing paralysis. You could imagine something similar happening with a SARS-CoV-2 vaccine: that it would block infection in the lower respiratory tract but not the upper respiratory tract, allowing you to spread it by coughing and sneezing while never getting severe respiratory issues.
