Or this?

For sure not that first sample.

The first one is all wrong. Too dark for the space, and the gray tone colludes with the pine.

Second one looks much better.

Thanks for your reply. The second photo I’m seeing is the dark gray. Can you see the marbled one above that? and then there is a third pic in the comments. Just want to be sure I’m understanding which pics you’re referencing. Thanks!

This compliments knotty pine well. Just a thought.

Couldn't see the first pic until now, so my referencing is indeed wrong. I'd still opt for the third one, the one in the comment.

The first one (the marbled one) is light enough and seems to have the right undertones, but I find it too busy to pair with the knotty pine. Although I can absolutely appreciate the practicality of a busy pattern to hide the dirt and wear in a high traffic area, so your call.

The second one is too dark and is the wrong shade of gray for those walls, at least on my screen.

The last one is light and understated, doesn't fight with the walls, doesn't attract too much focus to itself. Just a neutral floor that can work with anything, even if you do end up painting the walls in the long run. Maybe not be the prettiest, but is the most practical choice IMHO.

The only way to really tell is to bring in samples and see it in the room.

I’m going with large white-ish stone-look tile (24”x24”) for our knotty pine porch. I wanted something light in color that had an organic feel, but which wouldn’t show dirt super easily. Here’s a quick collage of the tile in the space and a pic of the tile. A few other elements in this space will change in addition to the floor (like the lovey fan light!), but this will hopefully give you an idea of the look!

I like the idea of a light natural limestone look and color on the floor. It will enhance the look of the knotty pine and look fresh for years to come. I would like a vinyl pattern without a lot of movement or pattern.
