Michael,
Enjoy your inaugural trip to France! My advice- don’t try to do too much. Spend enough time each place that you can relax and enjoy your time. Secondly, learn at least a few basic phrases/vocabulary in French. Making even a minimal effort makes a huge difference in how you are treated.
As far as Paris dining recommendations, https://www.wineberserkers.com/t/eating-and-drinking-in-paris is a great resource.
That thread is full of great information and excellent advice from lots of people with a ton of experience.
