Frankly I see no reasons to worry. 65min is a normal connection in CDG and airports are empty and flights empty nowadays.
AF longhaul flights are very empty. AF689 has been arriving on time and usually quite early (up to 1h). AF218 will wait for you, given the few pax, and will arrive on time even with a 20min delay.
Of course, there could be some technical problems with AF689 but then having a 65min connection like yours or a 2h will probably not make a difference.
The probability of missing your connection is really low.
There is a DL flight ATL-CDG two hours before. I would advise you to check that the AF flight is expected on time into ATL (from CDG) and if it is very late, go to airport early and AF will put you on the DL flight.
