I am assuming the ones advocating a wooden floor have rabbits as pets only and/or are warning you about sore hocks. Wire .5" x 1" galvanized after weld is durable, allows rabbit waste to pass down through, and does not cause sore hocks in a vast majority of rabbits.
I have a doe that came to me with sore hocks and she healed on wires. That said, it is advisable to have a resting place off the wires. We have warming pads for winter that we leave in all the time, easy to clean and they do not chew them up, but large floor tiles can also be used and they are cooling in the summer.
I would NEVER raise a rabbit on a wooden floor. For one, you will end up cleaning it THOROUGHLY every day. It will get urine soaked, which is quite unsanitary and possibly will cause mold, besides the fact that your rabbit will be constantly urine stained also. Even if you use a litter box, you still have to clean the floor daily. While rabbits will urinate in one specific spot, they are not as specific when they poop. They poop when they are eating and when they hop around. You will have to clean the floor every day.
PROPER wiring is the better choice for sanitation and the condition of the hocks.
