US/Brazilian moving to Portugal Question

I am a US citizen married to a Brazilian National (also now a US citizen). I am looking to retire/move to Portugal in the next 8 years and have been looking into the different golden visa options (or other options). I wanted to know if A) Because my wife is brazilian (no-portuguese parents/grandparents) and I have option to get brazilian citizenship later on through marriage, there would be a better way of gaining residency/citizenship in Portugal. B) I know there are reciprocal benefits granted to brazilians residing in Portugal such as healthcare, education, etc. What exactly would we receive over what the golden visa would provide? Thanks!
