I think one of the “charms“ of Argentina is the fact that it is still — not sure if for long — one of the very few places in the region with a middle class so when you move here there is no apparent socio-economic disparity, which can be extremely uncomfortable and distracting. Don’t get me wrong, there is plenty of inequality but generally not as bad as some other LAtam countries.
Now based on what you are describing I am not sure Argentina is the right fit. Argentina is cheap now but only if you consider the blue rate, but how long will this last? No one knows. I would second that Uruguay is probably a better fit. I wouldn’t live there since I find it incredibly dull but in your case it sounds like a match. Another option might be Colombia, nice climate and cheap, Spanish accent is beautiful and close to the US. If you chose carefully safety should not be an issue.
