I just did a transfer last week from 2e to 2g . While your transit to 2f is easier than mine was to 2G .as it is a satellite terminal, I suggest you avoid any CDG connection options under 2 hours. In fact for us, the ideal transit time at this airport is 2 hrs 30 to 3 hrs. Elapsed time gate to gate for us was 1 hour 45 minutes (I timed it exactly). And, where possible we walked at a brisk pace. First, there is no guarantee of a jet bridge upon landing. We parked at a remote stand and then had o wait on the bus until most of the plane unloaded. It was approx 10 minute bus ride to the terminal. We had to go through a very long security line only to be then faced with a longer still passport control line. Then it was the long trek to 2F. At that point it was at least 1 hour 30 minute elapsed time from deplaning. We had the extra hassle of another bus ride to remote terminal 2g. You will likely avoid this as 2g departures seemed to be on AF subsidiary HOP. In the past when we connected to mainline AF Schengen flights, departure was from 2f. We encountered many people on either the security or passport control lines that were in the process of rushing through to make tight connections. Yes, you are likely to be protected onto the next flight to BCN but why risk the stress? Better to accept a longer transit time and relax in the lounge
