I'd look into placing rubber mats wall-to-wall (horse stall mats, or those rolls of auto workshop mats--TSC) if not too heavy. They can be dragged out, hosed off, air-dried and put back in, lasting many years.
Over the mats I'd do a deep layer of large flake pine shavings (again, horse stall). Easy to pick poop out of with a litter scoop, easy on the feet, no jumping down onto a hard surface, easy to refresh as needed.
