Generically:

- shedding of responsibilities (no longer an expert)

- shedding of preconceptions (new people, new me)

- being new means that people are looking for you to bring your new perspective, which isn't always the case at an existing role

- working with all new people polishes management skills as you can't rely on built up relationships

And then there's the choices you make when interviewing about what kind of company culture/new manager/new team you're going to. Like, if I care a lot about DEI/4-day work week/etc, and my current company doesn't, do I want to work to make that happen (if even possible), or go to a place that also cares about that which allows me to learn and iterate on something that I care about.
