I’m honestly unsure how personal preference enters into it. For the vast majority of the planet, within an acceptable margin of error, 0 - 100 F will be a useful temperature range for almost all naturally occurring outside temperatures.

As for personal preference, I think the first two thirds of that range are unbearable. I grew up in an subtropical area that regularly rises over 100 F in the summer. I don’t go around pretending that’s not hot though. It’s very hot! Unless you’re proposing different temperature scales for every climate, I’m unsure how your point about your local area is relevant. Surely people travel outside of your (and my) warm climate.
