Trish, I just installed French Oak, wire-brushed, wide plank, and it's 4 MM , 9/16" thickness, and 8coats of finish. I'm surprised at how durable it is.
It's California Classic-Mediterranean-Granville is the color. (they have 10 other shades in this line)
I've spilled all sorts of stuff on it, the cats claws dig into it, but it cleans up like a breeze. also a matte type of finish.
don't know if it's in your price range,,,I lucked out and got this at a very good, good guy price. under 7sq ft.
