Are the dots pegs in the floor, filled screw holes or what? Are you sure you can sand this floor without hitting nails? Some of the dots on are seams so I wonder.

I am really not sure. They feel like dots of hard wood placed into the wood, if that makes sense. Do I have to sand it before I stain? (I am a novice)

The dots are not on the seams

At least one, if not three in this picture are on or are very near the seam. I see now it is just a peg floor with narrow planks. I've had peg floors but very wide planks.

You do need to sand off the finish and stain the raw wood and then seal it all again otherwise the stain will wipe right off. Here's a link on how to get started.

The color of the existing floor is very nice, what are you trying to change? Yes it needs to be sanded to raw wood whether you want to go lighter or darker. It’s a big messy project.

I don't think you need to change the color of it just because you're getting a new table. Do you want to refinish it because it has noticeable wear spots? I will say it is a rustic style with the pegs whereas the table you're showing is modern. Those two things aren't consistent with each other, but refinishing it won't change the pegs. Is this house new to you and your style is more modern? If you use area rugs they could cover a good deal of the floor and you could leave it the way it is.

I agree with the above comment. You don’t need new floors for this table if your happy with the current condition of the floors.
The tones match fine.

I agree, you don't need to refinish the floor to match the table. The color of the floor is fine as it is.

It has a finish now, just a relatively natural stain and a matte finish, both of which are very nice. I like the floor much more than the table set.

Are there worn areas? One thing that can enhance an existing floor is a ‘buff and coat’ where they abrade the existing finish and add one more layer of poly. This tends to blend in scratches and damaged areas (but doesn’t eliminate them)

That is a prefinished floor, anything you do to it will be limited by that. The "bevels" will make changing the color a bear, plus the "pegs" are there to simulate face attached and plugged.

Thank you all. Yes, the floor is work and has some marks on it, but overall in great shape. If I don't change the color, what would the process be? I just want to freshen it up.

Get a pro floor finisher in to assess the floor and make a recomendation. Tough to tell from pictures alone.. He may be able to do a buff and coat (light sanding and new poly).
