i can only speak for Europe, never been to any other continent, but in Europe i am decently well traveled, if you want something safe and liveable with descent healthcare and you don't want to learn another language i would suggest some towns in the Netherlands in the urban area around Amsterdam/Rotterdam/Utrecht everybody speaks English, i myself considered moving to Leiden or Delft. look up "not just bikes" on yt for some examples of the living conditions there. one downside is the weather there, it is always windi and thus rather cold most of the times. another downside, although the urban area's are mostly beautiful the nature is not... there are no hills nothing interesting except for maybe a few trees here and there or some fields and rivers, this is the reason i will probably stay in my home country of Switzerland. another option worth considering but not as safe (but still safe compared to the us) would be Sweden, Denmark maybe Norway. i don't want to suggest my home country of Switzerland for bias reasons. but there is a reason i still live there.
