It depends on the tees and equipment. Assuming Legend tees and good equipment, I would say Congressional 6. If you get a good drive you should have a clear shot at the pin. (Personally I would never try to bump the ball onto the green by threading it through that little neck of fairway, bit if you do hit the water you should still get up and down for par.)
Others: St. George's 14, Bethpage 4 (with the pin in the middle of the green), Bethpage 13 and Oakmont 4.
A number of the par 4s at St. A's are drivable under certain conditions, but I wouldn't call them easy eagles.
It is easy to reach the green on the par 5s at St. A's, but very hard to stop the ball near the hole. On those holes it is often preferable to be on the fringe or fairway for a safe birdie rather than being on the green in 3-putt territory, 50 to 100+ feet from the hole.
(This is all leaving Cabo aside. It has any number of reachable par 5s and drivable par 4s. There are also a couple of good eagle opportunities on Whistler.)
