A lot of great suggestions here.

My two additions would be starting weekly one-on-ones or if you are already doing them, using them to roll out changes individually with each contributor

This allows you to individualise your approach but will also help you get to know your team better.

No one is so busy they can’t spend 30mins a week having a chat.

The manager-tools.com has good resources to help with rollout

Secondly, figure out everything you want to change and then pick three. Dont change a single extra thing until those things are done.
