What are people using to measure manager effectiveness across the org?

Our CHRO wants to start tracking how effective managers are, things like do they hold regular 1:1s, do they give timely feedback, are their team's goals on track. Right now we have zero visibility into any of this. We can pull some data from Teams usage reports but that just tells us who's chatting a lot, not who's actually managing well. Anyone found a tool or approach within the M365 ecosystem that gives you a real picture of manager effectiveness?
