William, in your scenario, first determining factor, for me, would be size. If small, then framed print; if large, then canvas. Another factor would be decorative use. If, say, modern, high ceilings, plenty of wall space, very large canvas really goes well, even unframed.
Another thing from your scenario, the price. The lower the price, the more goes to the print framer, less to the photographer; in your case, like 80/20. The opposite with canvas.
