I believe that Apple could make this (using more than one country/locale for purchases/subscriptions) a lot better to switch between, but hasn't done so for a long time. I don't think Apple will focus on this anytime soon though. I think the simpler workaround is to have multiple Apple ID/accounts, one for each country and linked to specific payment options. It still requires signing out and signing in, but it avoids restrictions (IIRC, something like 90 days) and the need to re-update payment information as with the other approach you mentioned. The subscriptions may not work when you're not signed in to the account associated with its country, but this is simpler than following many more steps. I find it silly that Apple does not even consider switching between two countries as a use case that would apply for quite a number of people (it may be less in percentage terms, but surely a large enough number in absolute terms).
