The advantages you give aren't directly related to the cards being real credit cards, though. Visa debit cards work fine all over the world, and with Stripe. (In my experience it's very common in Europe for debit cards to be dual network, domestic and Visa or MasterCard. I don't know about Germany, though.)

The real advantages of credit are spending money you don't have, and points/cashback.

You can get them with debit cards as well, depending on your bank account contract.

On some banks there are bank accounts with automatic credit, up to a certain limit of expenses.
