Do not use Subsurface color as part of your setup, that channel is associated with subsurface scattering, and if you drive the subsurface scale too high your floor will glow.  It is wood paneling, you do not anticipate any translucency through it.  It is best to omit it entirely.  The Clearcoat/Clearcoat Roughness channels would be the most practical for wood; although Metallic gives you some tremendous reflective shine, I disagree with using it at high values.  If you want to add a yellowish tint finish to the wood, I suggest using the Poser native HSV2 node that has the color chip accessible for tinting.  Show us a render.
