First, mint-mobile is specific in some way? That part shouldn't be a problem.
Second, you mostly get to choose one.
Small enough? Yeah, Unihertz Jelly Star is tiny. Maybe you try one of the foldable flip-phones, Razr 2025 allows you to mostly live in the outside screen.
Custom os? Is there anybody else than Fairphone these days?
Buttons? Unihertz Titan emulates old blackberry passports, so it might be too big for you.
I recently bought Galaxy Fold 6 and live inside of the Nixdroid terminal :D
