I checked for my country (France) and it was completely inaccurate. I have never ever ever encountered a pizza with frog legs (which is extremely rare to encounter a all but on pizza???!), red wine or jam (?!).

The other choices of toppings were not the most standards, and one of the most common pizza (Regina or Reine, with ham and mushrooms) wasn't mentioned.

If you wanted to go for specifically French ingredients, Roquefort is more common than gorgonzola (the 4 cheese pizza is usually mozzarella, Roquefort, emmental, goat... Not whatever was written), crème fraîche, or merguez as a spicy meat. A very French topping that is not too uncommon would be savoyarde, with potatoes, ham and reblochon cheese.

Also pissaladière isn't quite pizza, it's a different type of dough
