I agree with Glenn. I think a 17 ft aluminum canoe would meet your needs well. They're extremely durable and readily available.A lot of Royalex (no longer made) canoes were used in whitewater because Royalex can flex and slide over river rocks and spring back to life after being wrapped/pinned, perhaps at the cost of some creases.
You are not going to be paddling whitewater, so you might want to search for canoes that have only been used on lakes, such as fiberglass or other composite canoes. They are much, much less likely to be damaged, although really old ones with wooden gunwales may have rot. There's also nothing wrong with looking for a 17' aluminum canoe that is in good shape. Many of us started in aluminum canoes, which are pretty inexpensive on the used market and almost invincible unless bashed in whitewater.
I say "started" because your kids will grow up faster than you can imagine, and then they will want and have more fun in their own solo boats. And so may you. No one canoe can do everything, much less for all time and for all waters.
The canoes you're looking at, Campers, Trippers and the Blue Hole OCA are similar in shape to most aluminum canoes.
Bonus, if you don't have indoor storage aluminum is wonderful because it doesn't rot or degrade in the sunshine.
