How do you structure Meta Ads campaigns for multilingual countries?

Hey guys, I need some advice from people who have a lot of experience running ads in Europe, especially in countries where multiple languages are spoken.

I have my own ecommerce store in the Netherlands with my own inventory, and I want to start selling in the Dutch-speaking part of Belgium as well because all of my ads are in Dutch.

My idea was to target both the Netherlands and the Dutch-speaking part of Belgium in a single campaign. Then, if I'm able to scale later, I would create a separate campaign for France and include the French-speaking part of Belgium in that campaign instead.

Does this approach make sense, or is it better to create a separate campaign for each country?
