A good poly and an appropriate hardwood selection can do a lot to protect the floor.
Would I ever do a natural wood floor in a kitchen or full bathroom? Absolutely not because I actually use a kitchen and have a dog that would maul hardwood with zoomies.
Albeit in a well climate controlled area. High humidity isn't good for bamboo. I used to work with a manufacturer whose warranty for bamboo floors had high requirements for humidity, which basically eliminated my area if you like to keep your windows open. If you are in a well climate controlled area, it's awesome and renewable.
Carpet is much more resilient to moisture, as long as it gets dried back out - that's why it's so popular in basements. Tile and vinyl plank also hold up really well to lots of moisture. Wood Is ok with humidity, it will expand and contract, but immersion will destroy it.
