The city tourist circuit gets old fast, you're just ticking boxes at that point. Walk up the Eiffel Tower, see the Mona Lisa behind bulletproof glass with 500 other people, eat a croissant, congratulations you did France. The actual memorable stuff happens when you ditch the plan and end up somewhere random. You can rent a car in France here:

Some will even meet you right when you land and hand over the keys so you're not wasting time at counters. For driving, Champagne region's loaded with vineyards you can visit, or Giverny has Monet's gardens and looks exactly like his paintings.
