Been asked before but could you please put where you are from (eg UK or Ireland or a EU country) when asking this.
Assuming you are from UK
You can only get an S1 if you are relocating, that is living in an EU country permanently, not for visiting. It transfers your healthcare from UK to the country you are going to live in and you need an address in your new country. You cannot pass it back and forth.
You require the GHIC card for visits which as replaced the EHIC.
The same with the visas. Unless you are getting a golden visa then you don't need one for stays up to 90 days in 180. There is no visa for extending the visits.
Any visa you get will show a willingness to become a Spanish resident and a commitment to living there. If you are thinking of getting one for extended stays then there simply isn't one. The NLV means you can't leave Spain for more than 10 months in the first 5 years or it will be cancelled. If you do stay more than 6 months in any one year with a visa you will be classed as a tax paying resident and pay income tax in Spain on your worldwide income.
A non EU citizen cannot stay for extended periods unless they take out residency and EU citizens don't need a visa.
