I am married under the community property regime, but the family home belongs entirely to me. I have two children from a previous relationship. I’ve been told that if I were to pass away, my wife would have to leave the home. Is this true?

No. Pursuant to Article 764 of the French Civil Code, the surviving spouse may request a lifetime right of use and habitation (droit d’usage et d’habitation viager) over the property that was effectively used as the couple’s main residence at the time of death.
