I suggest Brazilian Jujitsu. The rolling aspect of training trains you mentally to not to panic and problem solve the situation, deal with pressure, build cardio and relearn how to breathe, and adapt to different body types. Unlike striking martial arts, less worry of CTE.

In regards to what can be learned in an hour, a roll with someone gives you an idea of what it is like to be on the ground with someone in a fight without striking, biting, eye gouging, etc.It is a decent simulation if what would happen when on the ground and the idea that if someone doesn't honor your tap, you can be in big trouble.
