Can I use a 60 amp breaker for a 50 Amp hot tub?
The 60A breaker is protecting the wiring to the subpanel (and its internals). You can do this if you want and you will be perfectly fine.

Can I use a 50 amp breaker for a 40 Amp hot tub?
The 50A size is more common for spa tubs than 40A so if you ever want to replace this one you’d have a better chance of being able to re-use the wiring. As spec’d a 32A load can be installed on a 40A circuit, so you would have been ok with that.
