Should I fill a new install?

[acarly]

Hello,
I just wrapped up installing 1500 sq ft of 4” white oak. I’m debating on filling the floor, there are some gaps in not super proud of but most the floor is good and tight seams. I know filling an old floor is not recommended but kinda torn on this new install. Thanks for any knowledge you can provide.

Do you have any photos?

This is the section I’m least proud of. 1/16 gap at the top of the stairs. I live in mn so lots of temp/humidity swings. If it pops after a couple years, how much of pain would it be to fix and or look at?

It’s one board. Prolly easiest to bite the bullet and just replace it now.
