We can't speak to all polyurethanes, but in general, natural oil finishes like Rubio Monocoat, AFM Naturals Oil Wax or Bioshield Hard Oil are far more porous, i.e. permeable and breathable. However, finishes should not be a solution to excessive moisture issues in your subfloor. Proper vapor barriers beneath the floor joist and/or beneath the flooring are required by most all flooring manufacturers. Also, humidity control inside your room is also paramount. The National Wood Flooring Association recommends ambient relative humidity to be between 30-60%. This is required for the health of you, your pets, plants, furniture, cabinets and flooring. Without these measures, just using oil may not solve your problem.
