Wood, vinyl, etc will all need expansion gaps. Even glue down product has expansion requirements (although MUCH less than floating). I've seen the sleek/modern 'no baseboards' look. It normally starts out with drywall that is hung higher and properly FINISHED (reinforced). The flooring is then allowed to run UNDERNEATH the drywall. Or there is tile. Or there is glue down cork flooring. But each will require a bit of expansion at all walls. Tile and cork can be caulked at the edges....but the expansion gap still must be allowed. Have a close, hard look at the tiles that are already in place. How are they finished at the walls? How much space has been left? Is it the width of a grout line? Are the current grout lines quite wide (1/4" or wider?)? It is entirely possible to get a finished concrete floor in there OR linoleum (Marmoleum) to keep the MCM features going. Engineered hardwood or vinyl plank will be difficult even with glue down.

I had always loved hardwood floors and wouldn't consider anything else... Until we bought our current house. It has LVP (Coretec Plus) that visually is pretty good at fooling people into thinking it's real wood. When you walk on it, you can tell it's not because it doesn't have the echo of wood. But it also doesn't have the hollow sound that I remember Pergo-type floors having. Since we have an open floor plan, it is actually nice that is is a quieter flooring. We found a box with a few extra pieces of the flooring in the garage, and decided to test how hard it was to scratch/damage. Hubby dropped an ax on it, no marks. Then he "chopped" it with varying degrees of strength and it really took a solid blow to do damage. He also took a screwdriver to it, dragging the tip of the tool across the "grain" of the LVP (the grain is raised) to see how much pressure it took to create a visible mark, and again, it took significant force to make a mark that was noticeable. And with all of the marks that were eventually made, they all maintained the same color under the damage, so they weren't terribly noticeable until we held the plank up in the sunlight at the right angle. So I'm not pretty happy with the flooring, especially since we live in a mountain climate (snowy, muddy) and have large dogs. I think it will hold up very well. I have no experience with other brands though.

Trying to decide btwn the two. We have an active household of kids and a dog. Would like durable , easy to maintain wood-look product for our floors , that will last a long time . Any advice appreciated!

I don’t agree that LVP is not a good choice for basements. We used it because we have a walk out that goes to a free access dog run with 3 big dogs and the other entry is to the pool so lots of traffic with wet feet, muddy feet and at the end of the day a quick mop and it looks like new 12 yrs later . Hardwood would have by now looked like garbage from dog nails and water left sitting. IMO you choose flooring to stand up to your lifestyle not because some imaginary buyer will like it better. We have always had floors that are not real wood because we will always have big dogs and no matter how careful you are they can do some real damage to wood floors.
