A Prime and Netflix account will work in ANY country where they are available. No need to change anything for this.
Content made by Prime and Netflix will be available in all countries, but third party content will differ from country to country, due to how programme rights are bought and sold on a country by country basis. For example, in the UK Prime have access to a lot of the tennis. In Europe most tennis is with Eurosport (try Eurosportplayer).
But if you live in Spain, and want UK content, then you will need to have it registered to your UK address, and use a compatible (many get blocked) VPN / SDNS service to hide the fact you are trying to watch UK only content from outside the UK.
But prior to Brexit, you could use your UK Prime and Netflix account in Europe to access UK content without the need for a VPN / SDNS service, but for a limited number of days only. This was more for holiday makers and short stayers, not expats. But post Brexit, this is no longer an option for UK accounts.
