Westbound flights timed like this are generally not considered a redeye in the true sense as passengers would typically go to a bed in LA upon arrival and sleep a normal night before working the following day.
That said, I do not believe there is an appreciable difference between rows 2 and 4. And there is a priority security queue in JFK, though I have no idea if it'll be open that late. From a dining perspective, I think the full meal service is still offered on that late departure, but I'd probably skip it. Assume it'll be 11:30-midnight by the time food is served. I get hungry several hours earlier than that and would eat a full meal either in town before heading to the airport or in the terminal prior to boarding. If I got hungry during the flight there are plenty of options to snack on. But if the passenger really is going straight to work at 2a from the airport I'd be focused on sleeping during the flight, not eating or drinking.
