In disgust, Beethoven blotted out his original dedication on the score, "To Napoleon," and replaced it with, "To a Great Man."
So: fitting, that Eroica was not featured.

I doubt that anyone in France would have been playing Beethoven at the time. Not in the French court, opera, or in the armies.
I would count it a plus if they play “l’oignon”, “Chant du départ” or “La Victoire est à Nous”.
Or a fair bit of Italian opera! Perhaps something by Paisello, who is today quite unknown. He also seems to have been fond of this -

A very interesting article on Napoleon’s musical tastes - https://www.napoleon.org/en/history-of-the-two-empires/articles/air-and-graces-napoleon-and-vocal-music/#:~:text=Napoleon%20especially%20loved%20Italian%20vocal,%2C%20Paisiello%2C%20his%20official%20musician.
Military officers were disappointed with the coronation as well and some actually attended under duress. The event was carried out in a way that matched the pomp and splendor of Bourbon times. Many notable Marshals and other ranks had held on to their ‘republican’ spirit and the idea of a crowned head of France certainly didn't go down well.
There is a story that Marshal Ney attended the coronation and was surly the whole time, mumbling and obviously disapproving. At one point he said (loudly enough to be overheard) ... “Two million Frenchmen died to put and end to this kind of s*&t.”
