Best areas and school options around Montpellier

Hello everyone, we are considering moving to Montpellier as a family. We have two boys soon to turn 8 and 10, who speak French fluently. However, they have always been to English speaking schools, so their written French is not as strong as it could be. Wondering whether to choose the local public schools (perhaps with 'section internationale') or the International Bilingual School in Baillargues? Any idea whether the Bilingual School in Baillargues is worth the money/has good reputation? Alternatively would you recommend Saint Clement de Riviere, Saint Gely du Fesc or Castelnau le lez? We are looking for a quiet family life in a nice setting, with easy access to Montpellier and activities around... Super grateful for your guidance. Merci!
