We have hardwood on our main floor and LVP on our stairs down to the basement as well as on the basement floor (over cement). When the LVP was first installed on the stairs (it's been a little over a year now), my husband thought the "lip" part of the stair treads (the bull-nosed edge piece) was not installed perfectly flush and secure on several (I think 4) of the treads, so I wonder if that is not uncommon and is what your flooring contractor is worried about. I didn't even notice it, but my husband is a perfectionist and it bothered him. Rather than complain and have the installers come back to address the issue, my husband fixed the issue himself. I think he used tiny little nails (with no heads) to better secure the edge pieces to the adjoining LVP pieces, and I used dots of acrylic paint from my art supplies to cover the bitty nail holes. We have never had a problem with them since and we are up and down the stairs many times daily so they get heavy use. Just wanted to mention our experience in case that makes any difference for your decision. I don't regret using it on our stairs. We picked an LVP that coordinates pretty well with our upstairs hardwood in color, just a little more rustic which fits our basement vibe. We didn't want to introduce yet another type of flooring just for the stairs.

I don't have any experience with that specific floor, but I have sold dozens of Happy Floors tile floors and have never had an issue or claim with them. My in-laws put it in their 3 season porch. They love it and have not had any issues with it. About the only issues there are with porcelain floors are if the tiles arrive broken.

Chamois from Mapei and I'm not sure on the grout line size, I asked for as thin as possible. We have kids and have no issues so far. Our dog is an outside dog but he has come inside a few times and no claw marks or anything.
