Topic "Advice on engineered floating flooring" a message from mein1

Before we buy flooring, I am trying to learn more about it and I am grateful for any information you can give me.

We live in the Pacific Northwest.

Our house has 3/4" OSB subflooring. Because of OSB's problems holding nails, we are thinking of floating flooring. Of approximately 900 square feet of flooring needed for our split-level house, a small portion would be installed in the basement hallway and closet (over a crawlspace and OSB subflooring). The majority of flooring would be used for the dining room and livingroom on the second level, also over OSB.

We would have the flooring professionally installed.

I would be grateful for advice on what brands would give us the best chance of getting a floor that would last and wouldn't buckle. We would be looking for these features:

thicker wear layer that could be sanded if needed in the future

good locking system

Any advice on the best edging: beveled or straight?

Our furniture is not abnormally heavy, but I worry about click lock flooring coming apart under stress. Can this be prevented?

I believe a lighter shade of wood would work best for us and wonder what type of finish might not show scratches (we have a small dog).
