First time Paris travelers would love to hear about peoples favorite places

My husband and I are headed to France for our 1 year anniversary. We will be in Paris for a few days and I was wondering what was everyone’s favorite spots for food or sights. Any off the beaten path things that were cool, maybe some romantic places. I’ve done research but would love to know about people’s experiences. We love art, gardens, parks, fine dining, cheese, architecture, and history. Just to give some ideal but anything you found wonderful id like to learn about. Thanks in advance!
