Either water based or oil based aliphatic urethanes are non yellowing but exposed to sunlight even briefly pine will yellow, and other timbers like cedar will bleach. On a floor oil is a bad idea, it gives no protection to the timber and depending on what its thinned with can cause delamination or if in a damp area possibly mould.

I have not found this with my own boiled linseed oiled floors. They are hard and dirt resistant. I have Oregon planks as flooring not pine ply which as we all know will be softer. I guess the question is what is going to give a hard non marking surface for a floor in a hut where the OP is not likely to be wearing his slippers
