By car from Essen (NRW) to Marseille (F)

Hello together, my friend and I would like to drive from Essen to Marseille (F) together with the car…because we have never done anything like this before, I would like to know from you what it looks like with the tolls in F, which route is best and what it looks like with the borders in themselves…these are open, right? Once the route was entered at Map24 and there I was told that we should drive over Luxembourg…we would then be there in about 12 hours…must I have other Sach ? traffic rules and driving style of the French e.g.? many thanks already in advance for the help 🙂 LG
