What would I do?
If I loved the house and wanted to future proof and didn't give a shit about imaginary future people.
Take out the door to the utility or make it a pocket door so the kitchen sort of flows into the next space. Refit the whole area to suit you -
Nearest the breakfast room to become dining space
Sink, bin, dishwasher and shelves for everyday crockery, don't forget you can raise a dishwasher to make loading easier.
Hot drink stuff together, on upper shelf mugs and ingredients near kettle or hot tap.
Cooking - oven & hob with drawers nearby for saucepans and utensils, sieves, etc
Prep area- work surface with drawers, all your prep tools that you instinctively expect to find them rolls of foil. Etc, tupperware,
Pantry - tins and dried goods, could be in utility.
Tall open shelves with ready, daily use pet food, daily gadgets like toaster, bread, open sauces and chutneys.
Well thought out shelves/dresser probably in current breakfast room with all your serving dishes.
Ruthlessly declutter, now is the time.
Make dining room into bedroom, knock through under stairs to make cloakroom into ensuite with shower.
Leave upstairs for guests and dustbunnies.
