Hua Hin - what is the advantage of living there? How is the medical? Are there other Filipinos living there? Thanks

Hi all need a bit of advice my wife (thai) and son dual passport holder are moving to Hua hin in the next few months we currently live in the uk and I’m not sure what visa I should apply for I’m 56 I have the 400.000 I’m my thai account already do I go for retirement. Or as a partner visa if there is such a thing and do I apply in London or wait till I get to Thailand and what is the best visa to go for like the least hassle one that keeps me away from immigration offices thanks in advance
