> Definitely got carried away. When coming to a new org, it's always good to learn the ropes a bit before fatiguing the team with more work, processes, and burdens.

This is probably the single, most important advice for any new person joining a company in a (technical) leadership position. There are going to be missing things in any org, and bad mistakes, and people needing to learn new things. But also there are going to be tons of decisions that make "no sense" on first look that do have a reason behind, and to fix that "root cause" you probably need a 3 years plan and buy-in from C-level. So, trust the team you are going to lead.
