General questions re printing on canvas.

A couple of weeks ago I had the good fortune of buying a slightly used Epson Pro 3880 which had been use to print fine art on canvas. The owner showed me one of his prints & it was very impressive but not something I'd be doing but he included a decent quantity of canvas along with fine art paper & a bit of Epson photo paper (I already have a good assortment & an R2880). I've tried to read up on printing to canvas which seems to be very popular but have a few questions about the types of photos that look good on canvas.
What looks good & why? I've got a lot of family photos from baby pictures to anniversary photos & will soon be shooting the 65th wedding anniversary set for my mother & father in law. Lots of collector car photos, primarily Corvettes plus lots & lots of model aircraft in flight & lots of underwater photos while diving.
Also should they be processed a bit differently vs when printed to glossy or lustre photo paper?

IMO canvas tends to make average shots look good, rather than good shots look great. It's also good for huge (e.g. 36"x108") prints, because it's relatively cheap for large areas (including price of mounting, which rapidly outstrips the price of printing at larger sizes), because stretched canvas is lightweight, and because canvas' significantly lower resolution than paper or metal doesn't matter at such huge sizes.

For more typical sizes, I tend to avoid canvas.
