Best “Smaller” Cities to Move To?

My Partner and I are looking to move out of NYC. We’re looking to have more space, better quality of life, and ability to save. We have explored Denver and Austin and have spent many hours online looking at cities. This move will be by no means permanent unless we fall in love with the city. Ideally the weather will be more moderate, without the scorching heat of Austin, or the cold northeast and Midwest winters. I know this limits our options, our budget is approximately $3,000 a month.

What we value: Space, this is a must for us as we work from home

Gym, we both enjoy working out and value a gym where we can get a complete workout.

Decent food scene, I cook and can be content with maybe 5-20 decent restaurants.

Access to vacations: whether local or a good airport

We don’t really drink but I partake in the greenery, but legality isn’t a deal breaker for me.

Any thoughts?
