Enduro-var on 100 year old pine kitchen floor?

I just finished sanding our kitchen floor. I had to rip off two layers of underlayment and two layers tile to get to the original wood; which turned out to pine. House is from about 1910, so this is older pine. The guys putting in the underlayment must have been paid by the nail; they drove in a lot of them. I’ll try to post a pic.

I wiped some water onto the floor to show my wife what a clear finish would look like, more or less, and she liked it. That means no staining, which works for me on all levels.

After doing a lot of reading, I am leaning towards the enduro-var, which is supposed to give the amber tone (or close to it) that I’d get from traditional, oil based finishes. It seems easy to apply. So, a few questions:

1) any one have any experience with enduro-var on floors?
2) semi-gloss vs. Satin? Or could I even go with a full gloss?
3) any other option that would also be water based? I like the low odor, easy clean up, etc. I have used a water based finish from Lowes, but it lacked the amber tone, so I’d prefer something like the enduro-var.
4) I plan to leave the nail holes. There are a lot of them and I think filling them will only make them stand out. Thoughts?

Thanks!
