Temperature is most of your problem. Finish is too cold to release the air bubbles, Get it up in the 60’s. Try a foam brush and lay it on in one direction, don’t brush back and forth. The haziness is just the sanding of the gloss off the finish. You may have to put several coats sanding between coat to get the bubble pockets filled from the first coat. You need to get the temperature up.

I am not a fan of Minwax esp. their polyshades but I just finished a desk with Minwax polyurethane semigloss and it came out really nice. It took about 5 coats total on red birch to get the thickness and coverage I wanted. I used cheap foam brushes and had no problems with bubbles air temp in shop was low to mid 60’s. I would use the Minwax polyurethane again.
