I’d suggest go to a boxing gym. Boxing is superior for self defense and builds a great physique. It’s also the most practical form of fighting for regular people.

Brazilian Jujitsu is the best type of jujitsu as it teaches takedowns and grappling. Both of which are extremely useful for real life street encounters.

Sadly as for verbal deescalation there isn’t much outside of security guard training/employee exercises. Probably because verbal encounters are very situational and depending on the mood of persons involved.

Whereas physical is usually always the same regardless of mood.
