I've taken the FLR-CDG flight. You park on a regional jet tarmac and have to take a bus to 2F. So add about 10 minutes or so to your connection time for this. It'll take 5 minutes to get from where you enter 2F to where you meet the shuttle. The shuttle runs outdoors on the upper level (check-in level) and there are signs telling you where to wait for it. Depending on the time of day it should be no more than a 5 minute wait for the bus.

The reason for the Florence flight being late is usual due to winds coming off the mountains above the airport. When I was leaving we had to wait 20 minutes for the wind to die down. It could be close, but you should be able to make it.
