2 years ago we did our kitchen and used yacht varnish. It's very hard wearing, waterproof and can choose to get it shiny or not. I'd go with that but others may have a different opinion. I'd argue the yacht varnish will only need re-doing every 10 years or so with a light sanding then add a coat.
Yacht varnish will be pretty stinky for a while; the products that won’t be will water based, so less effective at preserving the wood.
