Magnus, lots of good advice and info in this thread.
As a sitter I agree with Charlie that round bottom canoes can feel twitchy uncomfortable for seated paddlers. If you are a habitual sitter taking broadside waves or making sharp eddy turns will require a wet learning experience.
Like Willie I have an OT Penobscot, soloized with an Ed’s Canoe Parts contour seat (and truss hangers, not those awful dowel things OT uses), positioned well aft of center. That is my big guy, big load go-to canoe for long trips, but like you I have a bad back and questionable knees, and the weight is enough that I don’t want to have to carry it further than truck to water.
I believe it was Charlie who once advised “If your back is getting stronger buy a plastic canoe, if not, buy composite”. I should have paid more attention to that dictum 20 years ago.
Some of the criteria depend on your packing style. I don’t portage much and tend so to pack gear heavy on solo trips; “two” person tent, full size camp chair, tarp and poles, blue barrel, some libations, etc. I have an MRC Freedom Solo (nee Guide), which I love for moving water daytrips, but packing gear for a multi-week trip in a 14 ½ foot hull would be an awfully tight squeeze or above gunwales load.
I also have a Wenonah Wilderness. It is no more maneuverable than the Penobscot and I would just as soon have the Penobscot’s extra foot of length. The Wilderness is the RX version and it oil cans a bit; if I had it to do over I’d buy that canoe in Tough-Weave.
As a Wenonah downriver tripper I am partial to the Rendezvous (15 feet 8 inches with 2 ½ inches of rocker), although again one of the composite versions is preferably to the Royalex model. The composite Rendezvous paddles substantially different than the RX version. One caveat with the Rendezvous; some people find the low chine-bubble tumblehome awkward. I would definitely put the Rendezvous in the difficult try-before-you-buy category.
There is more information about solo tripper canoe preferences on this eponymously titled thread, including a Glenn MacGrady list of models on page 3 that would largely suit my preferences.

I am too cheap to buy a new canoe, and the list of used canoes that are not unicorns on a mid-Atlantic region Craigslist fitting my bill as design solo, soloizable tandem or bow backwards boat is relatively short. In Royalex the ubiquitous Penobscot or (less common) a Dagger Reflection 15 with “center” seat, in composite a Rendezvous or an adapted MRC Explorer or Malecite probably make the most used appearances.
BTW, I am fond of paddling in eastern NC. The State does a nice job with Wildlife Boating Access points and with their paddler oriented State parks; Merchants Mill Pond, Lumber River, Hammocks Beach and etc. For blackwater swamp day tripping the middle and lower sections of the Black and South rivers are hard to beat. I’ve done most of the South excepting the very top end, and all of the non-tidal Black.
If you do not yet have a copy Paul Ferguson’s “Paddling Eastern North Carolina”, covering 2600 miles of NC rivers, that guidebook is a godsend.
