> not have things like healthcare tied to my job which only seems feasible by leaving the country
You probably won't get state-provided health insurance the moment you move in, without a job, anywhere. Though a lot of countries won't let you die, you will assume more cost than you think (or be deported back).
At least in Spain, private health insurance is ~$1k/year as an expat. This covers almost all of your medical costs without copays, deductibles, etc. I have personally received this quote as an early 40s male with no major medical issues.
Not just that, but you can get health insurance not tied to your job in the US. It costs some money, unfortunately it is tied to income, but if you're planning on lowering your income to improve your quality of life, it should help quite a bit on the healthcare cost side of things.
Unfortunately the plans are extremely low-quality in some states. In New York State, for example, the 'marketplace' plans are ALL HMO's with high deductibles, and the networks are small. The state has some of the best healthcare in the world, but good luck if all the care you want is out of network.
AND it costs up to 1K a month for a single and double for a family.
