I've been using iPhones since the 3GS, and honestly, the last time an iPhone felt truly innovative to me was the iPhone 7. Since then, it seems like developers have been more innovative than Apple itself. But that's just me. Maybe you have found something innovative around your workflow.
Off the top of my head...
For me (a photographer)... Much better cameras and options. Being able to shoot in Pro RAW providing much better post-processing dynamic range and detail in Lightroom is killer. And recently... easily finding specific photos out of the 28,000+ images I have on my phone. For example search for "red cars with dogs and bicycles" or "beaches and surfers," "women with hats," etc. Also... the Photos app on my iPhone works great for remote post-processing when I don't have a computer/laptop handy.
Also... collision and crash detection with emergency messages automatically sent to responders via messages. Many lives have been saved via that feature. Being able to send a message via satellite if my car breaks down, or I run out of gas in the middle of the Mojave desert or Joshua Tree National Park where there's no cellular service. Fall detection alerting emergency services is also nice.
Edit:
Also... the Fitness app on my iPhone keeps track of my treks I take everyday accumulating loads of data (heart rate over time, calories, distance, workout time, elevation, a route map, etc...) from my Watch. I like that a lot.
