Will answer my own question for posterity, in case it helps anyone else. The MCT at CDG for 2E to 2F is 60 minutes, and as a result of my schedule change quoted below I was able to change my FB award to a different flight for no additional cost even when my new award itinerary now had a substantially higher cost in FB miles than my original. I'm amazed someone picked up right away and pleasantly surprised at the general competence of the person who assisted me.

I've had a somewhat similar change to departure time that has brought my connection to VIE down to 50 minutes (T2E to T2F) after my inbound AF flight from JFK lands. There's still another AF flight to VIE after mine, but involves a 5h longer wait. The AF website doesn't appear to see any issues with this connection, but from whatever I've been able to find, the MCT at CDG for 2E to 2F is at least 60 minutes. I'd have Sky Priority and no bags, but the prospect of waiting 6h for my flight seems to be not worth it.
