is there a way to get a list of all the results fields for every saved search type? I found a help topic list of all the join fields per search type but I'm looking for all fields including those join fields.

try the 2020.2 Schema browser you should have all native fields and joins https://system.na1.netsuite.com/help/helpcenter/en_US/srbrowser/Browser2020_2/script/record/account.html

I think this is exactly what I needed thanks! @Sam-I-Am
