Why not a semi dark stain. Super dark is super trendy and I love it. It's fine if you can vacuum daily and NEVER wear shoes in the house.
Personally I go for looks over practicality.
I wanted super dark and the sample of the stain looked dark but didn't turn out as dark as the sample somehow!!
Make sure you have a really good refinisher. Our floors were great until they messed up the last coat. We had to start sanding all over again!!!!!!!!!!!!
Had to move out. Clean up took HOURS. Furniture had to be moved (it arrived a few days after the floors were done the first time. We couldn't stop the movers once we scheduled the date)
Medium wood tones are awful - anything orange like is dreadful.
