The Pixel 3 I have I got used and it still works, although the back glass is broken and the battery health is 85%, and stopped getting updates around a year ago. I’d say it’s 5 years run so far (released October 2018) is pretty good. If you know of any other devices that would be useful for 4~7 years please share! I think high end Apple and Samsung devices would, and they are now committing to longer software support, and are likely to carry though.
Hope your life goes well in New Zealand. Leaving on the cusp of a new hope is an odd choice.
