So I will assume the Butcher block is maple - using an all in one water based polyurethane stains is going to be problematic with maple as it does not absorb color equally across the grain especially water based. I like to use a sanding sealer first then an oil based stain applied and buffed off after it sets a few minutes with a cotton rag - then after that has dried for a few days you can apply a top coat of either water based Polyurethane or my preference oil based polyurethane. If these are "food" service areas then I would use a food grade mineral oil only on the bare wood and just touch it up occasionally.
