What happens to my files in icloud (I'm using icloud+ ) when I change countries?

Does icloud count as a subscription? I'm trying to change countries on my apple ID. I've read that I should spend all of my credit and cancel all of the subscriptions. I remembered that I have a family shared icloud+ with loads of important files there. I was wondering if I'll still have access to my files once I've changed countries?

PS I've recently moved to a new country and bought a kettle here. The kettle has an app for remote control but I cannot download the app bc it's not available in my country.
