That looks like a very reasonable itinerary, in fact, it's very similar to the one I had when I visited with my fiancee in August 2017.
It was the second time to visit Paris for both of us, but our first trips were separately 10-15 years prior. Is it the first time you and your husband will visit? There are certain things for people on a "must do/see" or "must repeat" list (for me, it was the Louvre, I missed it my first trip, for her it was the Champs-Elysees experience).
This was our schedule, although given the summer hours, we could extend things much later in the day than you can in October:
Fri: (arrived CDG 9:30am from Seattle) Montmartre/Sacre-Coeur/Dali Museum/Moulin Rouge
Note: after dropping off our bags at our hotel near Opera, we didn't get to Montmartre until 3:30. It takes longer than you would think to get out of customs and the airport and into the city.
Sat: Sainte-Chapelle/Conciergerie/Notre Dame (inside and bell tower)/Ile St Louis/Latin Quarter/Cluny Museum/Pantheon
Arc de Triomphe/Champs Elysees/Eiffel Tower (11:30pm climb time): yes, this was a very long day!
Sun: Catacombs/Louvre/Seine River evening cruise
Monday Normandy full day
Tuesday Disneyland full day (we moved our Disney trip to this day due to an inclement weather forecast)
Wed: Army Museum/Napoleon's Tomb/Rodin Museum/Rue Cler/Orangerie
I went back to the Louvre late night, she went back to the Champs Elysees (alone time!)
Thu: Versailles (left at 3, it was roasting hot this day, so we didn't get too far into the gardens)/Orsay
Obviously, we got the Paris Museum Pass (6 day, started on Day 2), and a couple carnets of Metro tickets. Yes, I know we wasted 2 full museum pass days in the middle, but you can't avoid the Monday closings, and it was only 12 Euros more for the 6 day.
The Place de la Concorde and Tulieries really weren't that impressive, especially Concorde. You could probably open up your Wed morning a bit more. Rue Cler is an area I would predict Rick Steves would like, but it wasn't our thing (it seemed like everyone there was an American expat). Your Notre Dame experience will be a whole lot shorter than ours, so maybe you can fit a river cruise that first night. I probably would've wanted to spend more time exploring deeper into the Left Bank. But that'll be for another trip!
