Even though not asked for, maybe consider european cities, too, especially the bigger older ones.

They are not skyscraper-level breathtaking like many US cities and not as dense - but have lots of advantages (walkable, good public transport, rich cuisine, higher food quality in general, less homelessness or other social issues, … not even talking about working here with much more vacation/free healthcare/…).

Ultimately you mentioned museums - well Europe has stuff that is thousands of years old. Lots of stuff to see and discover. I personally like to go to authentic medieval festivals or viking meetups for example.
