Salut, JOUY31!
Welcome to FT and Delta Forum, wjudge.
I have had many transfers through CDG (grrrr..) with a little more or less than 60 minute connection time, mostly misses. The checked-in luggage was 99% miss. Don't recall going through customs, but security, yes, twice, and passport control once. The queues could be blocks long! I would definitely suggest a later flight to NAP if possible, for the peace of mind. Besides, the AF First Class lounge at CDG is very nice and relaxing.
Have a safe trip!
