I used to work in France. The 30 days is just the beginning. I ended up with 44 paid holidays per year towards the end of my contract. There are different types of paid leave and I got 9 days extra because one of my children has a disability.

However, the work culture in France is extremely toxic. You face a sort of social othering if you don’t conform with the unspoken rules which are even harder to understand if French is not your first language. Punishments include being managed/bored out and being “put in the cupboard” where you’re given a dead end role and basically left to rot until retirement. There’s a history of work related suicide in France.

Even so, you are a lot more free than in other countries. I’m not complaining. Plus, unions still have actual power there (although that is being eroded down)
