Ideas for VE Day?

Visiting from the US and just realized we will be in Paris during VE Day (May 8th this year). Are there any special events or sights we should try to see? We were thinking of taking a tour of the military museum in Invalides and/or visiting the Museum of the Liberation, but open to other ideas!

On the other side - if there is anything that we should avoid or should not count on being able to do because of holiday closures, that guidance would be helpful too. I understand some restaurants and shops may close for the day.
