I would suggest Orient. There are MANY short term rentals available including some small ones which would suit the two of you. Quite a few local property management agencies cross list their properties on AirBnB as well. There's enough stuff within walking distance that you can fill any spare time with beach walks, going for gelato, etc. since you like staying active. The area is a very quick drive to Grand Case for your sunset dinner night, and on other nights there are plenty of good restaurants in Orient Village, as well as a grocery store.
I would suggest Orient over the Maho area because on one of your previous posts I got the impression that your daughter is a minor, and so bars and nightlife won't really be on your radar. If that is the case, Orient will still have plenty of people milling around in the evening that you should feel safe going to and from restaurants and shops.
