You can do that on iOS! Swipe left on the notification and tap “options”, then you’ve got a couple options to control future notifications

I switched back to iPhone recently from Android and I do miss being able to silence, specifically, marketing push notifications when they arrive. iOS is either all or nothing unless the app itself lets you selectively turn off marketing push notifications (and they usually don't).

(Relatedly, if you're an app developer for some shop or other, and you ask for notification permissions "so we can keep you up to date on your orders!", and then the app spams me with marketing push notifications, it should mean that you and anyone else responsible gets a thousand years in the lake of fire when you're gone. Fair's fair.)

Everything else I don't miss really. My years of giving a toss about tweaking everything to be just-so are pretty much gone, just give me a sensible default that I can work with and I'm happy.
