The classic work triangle between sink, hob and cold storage still holds, with one addition that modern kitchens keep forgetting: a landing zone. Every appliance needs 40 cm of clear surface beside it on the side you open it from, and an island without one is a very expensive table.
The second failure is the run. A single galley wall of 4.2 metres looks generous in the drawing and means walking the length of it forty times a dinner. Break it, or accept the steps.
For hosting, the rule that changes the evening is the one about the cook. If the person cooking has their back to the room for more than about a third of the time, the party moves to wherever they are, which is usually the wrong side of the island with nowhere to put a glass down.
