IC Legrand is clearly your best choice, considering that the best HIs in Paris would require 25K Points anyway.
I was even upgraded recently to a Junior Suite on awards, even if i am no longer RA.

Unless you are flying on a week-end day or you are travelling in August, taking the Roissy bus at 9:30am could be tight.
Better give yourself a 30 minutes extra time.
Have a nice trip.
