What should I ask people at the program recruiting me?

[AverageEccentric]

Hopefully this is useful for folks in all fields ... For various reasons I declined campus visits and postponed the requested Zooms from recruitment offices, and I'm putting them all into one week later this month after I have all the info from all the programs.  I have offers, offer letters, funding packages, and graduate student manuals in hand.  After having read all of that, what questions do you all think are most important to ask: 

-- The advisor(s) you have been assigned: 

-- The Graduate Advisor for the program itself: 

-- The other grad students currently in that program: 

-- Other parts of the university to talk with / research BEFORE accepting (specific resource centers, financial aid, Disability resource centers, Veterans resource centers, Human Resources about the fine print on the medical coverage (in the US), Basic Needs Hubs for the many of us looking at funding packages and work requirements that barely keep a person housed and fed, other things that have a lot to do with quality of life when committing to a place for 5 years, rec centers, intramural sports groups, resource centers specific to certain identities or needs ...)
