I know that thread wasn't specific to idle behavior after a battery disconnect, but if my idle doesn't return to what it was before the battery replacement would 'running a good fuel system cleaner' help my specific idle issue? If so, is there a 'good fuel system cleaner' that you would recommend?

A fuel system cleaner won't help. Pick up a can of throttle body cleaner. The best way to clean it is to unbolt it so you can easily clean the entire inside of it.
