Become a student of psychology. If you're coming from an IC->management role for the first time, expect your worldview to be broken, and let it happen so you don't have to have a spectacular flame-out to allow it to reset (happened to me, and very common for people coming from the very unambiguous world of "code compiles" to the very loose world of human interaction, where people can't even understand their own motives, let alone anyone else's). Even a modicum of authority changes the way people interact and respond to you, and that's not going to change. Work within it, meet people where they're at, and understand that when it comes to dealing with reports, they're usually right and you're usually wrong.
People are the only thing that matters. Deadlines come and go, companies go bankrupt or get their entire C-suite arrested in midnight raids, competitors come in and break everything and turn the company into a zombie. The thing that endures is the people. If you have good people on your team, consider yourself lucky; being a great boss is one of the best ways to cement a lifelong connection to the best people, and you'll get way more benefit from it than you deserve.
Nothing is straightforward or face value. Understand this and don't try to change it. There's a lot that you'll have to learn for yourself, but keep your priorities and loyalties straight, don't buy into anyone's bullshit too far, and you'll be fine. Good luck.
