Good afternoon, @jfakenney.
Nice to have you here in the Community. I'm happy to provide insight into banking rules for you.
QuickBooks Online offers banking rules to categorize transactions in the Banking tab accurately. These rules apply to unaccepted transactions (transactions on the For Review tab of the Banking screen) ONLY. Meaning the categorizing only applies to transactions that are currently coming in from your bank that need to be accepted. This article on Using Banking Rules outlines how the rules work.
Should you need any further information, please do not hesitate to contact me. Wishing you continued success now and in the future.
