Recently, I have flown quite a lot with AF from CDG
Nov last year, to Mumbai and return, with A340, in business.
This year, Madrid and Moscow in economy.
All those flights have been very nice, with good catering, good choice of movies, and very nice crew.
About the cabin layout, I never had a chance to try their 777. But I think you will have enough space.
And do not worry about language. It is not because they will maybe speak French first that they do not speak English. Especially on a flight to the States and in Business !!!!
You are on a French airline, then all the announcement will be in French first. But everything will be repeated in English....
Yes, AF has been quite bad in the early 90s. But today, it is a really good airline. And they really care about their customers ideas and opinions: On each flight, they randomly select 2 or 3 pax in business, 2 or 3 in economy, and give them a survey to give all their feedback about the flight.
About the ATC ranking, forget it. I don't know how they do it, but when you see that LH catering is much better than SR, there is something wrong....
