For better or for worse (obligatory remark on how in a federated model there should be no “main” or “flagship” instance) that would probably be lemmy.world on the sheer number of users alone?

Not sure about Iceland, but several countries place some constraints on which foodstuffs you can enter the country with (not asking about importing, etc, even for personal consumption). I’d check this beforehand.

Undoubtedly! I was always more of a lurker, but I think I’ve posted as many comments here in the last couple of weeks as I did in 11 years of Reddit… Lemmy is, somehow, much more inviting.
