I just switched to an iPhone, what should I do to make the most of this change?

Basically the title. I've been an Android user since 2012, but have have an iPad and a Macbook that I really like, especially how well they work together. My pixel 5 was on its way out, so I finally took the plunge and bought an iPhone 15 Pro earlier this week. I'm still getting everything set up, and I'm particularly excited to play with the different focus modes and shortcuts. I'm curious what apps and features should I be using to make the most of this switch?
