This is quite a good report based on a reasonably large survey on diversity, equity and inclusion (DEI) in the workplace. If you want to 'pay' for your copy with personal information, click on the title link. Otherwise, it can be accessed directly from AWS (52 page PDF). The main takeaway, I would say, is this: "DEI is not a training problem – it’s a strategy and culture problem." Yes, training may play a role, but training in a barren field will produce limited and even negative results. There has to be an organizational commitment, led from the top, that permeates all business functions, and for with managers are held accountable. After you've done all that, you targeted specific training - not just DEI generally, but things like 'listening to employees' and 'inclusive practices in HR'.
