What's the best clear coat finish for wood stairs?

The treads and risers are all oil base stained, and as you can see in the riser's image, they match the floors on the main level. So, now it's time to coat with a satin finish. Being old school, I've always felt oil/oil is best, but what do I know ¯\_(ツ)_/¯

The stairs go down to the basement so they are not subject to heavy traffic besides dogs. I usually use a Polyurethane, so interested in opinions about alternatives or specifics while using the best.

Thanks for your time!
