Yes, I am aware of that. Eiffel Tower pics are not copyrighted (Gustave Eiffel passed away in 1923), only the lighting is, indeed.
I forgot to mention "works of art" in public places; there are no panorama rights in France comparable to those in Austria or the UK.
Otherwise, if you want to understand the finest nuances of French photography law, the related rulings of the Court of Cassation are publicly available, extremely well written (in French, goes without saying), and full of subtleties. I read though all of them, ten years ago...
Concerning the US, when I travelled there, I had a copy of the summarized federal photography laws on one A4 sheet in my bag, at all times, just in case... in France, cops do not care, but over there, I was not sure. Fortunately, I did not get into trouble.
