I have a friend who did this floor in her house. I am a flooring person and had to bend down and look and touch to tell it was not real. Great stuff. I like #1 best. Contrasts the best with the cabinets and seems to blend best with the doors and trim. It might make the space seem lighter. As lots of wood can darken areas somewhat. #3 is second choice as I like it better with every thing BUT your cabinets. It's ok with cabs as it has some dark areas and is a 'louder' sample. But seems more contemporary. I actually like it the best of the samples by itself. Just not with your cabs as well. Do not like any of the others. Not enough contrast with the other woodwork especially cabinets. #5 looks the most dated and unreal. Others seem too dark. I would keep the doors wood stained as they are but paint the trim. It looks like it needs sprucing up and with all other finishes changed will look more like it needs it. I'm doing stained doors and painted trim in our new house but realize others may not care for the look. I do like the vinyl planks though.

If your wooden subfloor is in really rough shape, install 1/4-in. plywood underlayment over it. ... If the floor is in decent shape, you might only have to patch a few of those holes. Here is a very good article covering everything you need to know. https://www.familyhandyman.com/floor/vinyl-flooring/luxury-vinyl-tile-installation/view-all/

@littlebug - I appricate your feedback, since I am open to others ideas. What color would you suggest? I do like the Scandinavian style, so I might be going with a lighter floor. Here are a couple of examples of brown furniture with gray walls, I find the look harmonious and pretty!

If you like warm color, this Elegance Plyquet Hemlock SPC can be a great choice for your decor. Hope you like it.
