Solid hardwood - a chunk of wood (3/4" thick usually) that is milled for tongue and groove. This will not work on concrete as already stated. It is the least stable of any option, meaning it will expand and contract with the weather and is less moisture tolerant.
Engineered hardwood - plywood core with a wood veneer (can be 3/8" to 1/2" thick). Plywood is more dimensionally stable so it can be glued, floated, nailed, stapled, whatever. This is the route I'd go if you want wood.
Laminate - HDF core with a paper image to create the visual, and a wear layer/texture stamped together. Generally they are very durable but can swell if the are submerged in water. However, they make these in water resistant styles where the core is immersed in resin to make it more tolerant.
LVP floating - The recommendation above for Coretec is a good one. They were the first to come out with a composite rigid core LVP and it has a cork pad attached. There are a ton of products that are similar but I think there's is the most reliable. That stuff is easy to install, is inexpensive, looks good, and is durable.
This is correct, but a little inadequate regarding the laminate flooring.
Older laminate floors were essentially a paper picture of wood on a composite backing. I am not sure if these exist any more. They were very prone to damage and failure. They were junk, and laminate has shifted away.
Much of the current generation of laminate flooring is sometimes called "embossed laminate". The decorative image is the second layer, under a melamine resin surface which is extremely durable. This layer is often embossed with a texture registered to the image underneath which looks very convincing as wood grain.
The core is HDF (High Density Fiberboard). It is usually in a color to match the decorative layer, so a scratch would be really hard to see. (However, I have tried to scratch the outer melamine resin layer, and it is extremely durable)
This material is marketed as waterproof, and I believe it. I have had standing water on the material for several days without damage or warping.
This is what I am referring to when I say "Pergo". Yes, it's laminate, but it is a far superior product to what laminate was a few years ago.
