Between the 4 available options, they should almost certainly be able to find you another D1/business class seat option over the ocean if you miss your flight. There also look to be same day arrival options to CDG via MSP and LAX that depart after 1:30PM. I'd say you are definitely overthinking this one.
Plus they can route OP to YVR/SFO to connect to AF.
