One Night in Paris Hotel/To Do Recs

I’m flying into CDG and will arrive at 9:30 a.m. Then I fly out the next day from ORY at 11:55 a.m. to Portugal for a week. I will be back in Paris for 6 days after Portugal (staying in Le Marais) and have been before. So just looking for a good neighborhood with light activities, dinner recs for a short first day! It will be a Friday. Thanks!
