Re: flooring for enclosed porch in MN
Stick with tile. As mentioned, wood will be problematic as humidity and temperatures change.
You could also do stamped and/or coloured concrete.
For tiles, the under layment must be rock solid or it will crack and lift. There's a huge wrap around porch on a old home near here. IT has gorgous hex tile with a really neat pattern. Sadly, the porch has settled and the wood has changed dimensions and buckled much of the tile.
