Just keep in mind that a lot of people equate Agile with Scrum, which is incorrect. Agile is about exactly what you said: empowering devs to get shit done. None of the extra “keep managers happy” crap that Scrum introduces is in any way covered by the Agile manifesto.

A lot of the ceremonies in general are mostly helpful to the EM/PM. How many things that you're doing are actually improving how you get work done? Especially when you consider how much time is spent on these ceremonies (sprint planning 1 hr, sprint retro 1 hour, daily standup 15-30 minutes. Plus whatever prep is needed and the interruption time.) For many companies this is a 20% or more overhead that's mainly busywork because you still need the additional meetings to understand what you're working on.
