Either the Beneteau ("Bendy Toy") or the Catalina would be fine for your purpose. Others like the Junneau would be fine, too.
The Swan 43 in your link is a great boat, but it would not only cost more initially....the upkeep would likely make you and the Admiral unhappy. Especially the teak decks.
For daysails and the occasional couple of week (or month) trips on the Chesapeake, just about anything afloat would work. Choose one in good shape which meets with your needs (and makes the Admiral happy), get a good survey before purchase, and go for it.
