>The Nordics are small enough to country-wide standards easy.

Size of a country has nothing to do with this. Neighbouring Austria is tiny and is also federalized, with each state having several degrees of autonomy and potentially causing various bureocratic nightmares depending on what you want to do.

Same with Switzerland and its cantons.

True, but I'd expect that those smaller units still have it much easier to pragmatically standardize procedure even when those are formally below federal than in larger units.
