Homeschool and learning another language

I attended and appreciated our local Homeschooling Parents’ Night (last night 01.27.2020). My daughter Isabella is going to be 10. She is concerned with continuing to learn French, so our goal is to continue to to learn another language at home and through travel as a family. Would appreciate if you’d please recommend a home-based curriculum that covers all subjects and may be best to help our family with our goal.
