I tried going back to a dumb-phone some years back. But that didn't quite work out, either.
One policy I had for a while was to remove apps that (a) I didn't want to use, or (b) I would never use and that didn't want cluttering up the phone's screen.
I have since moved on to my current system: I don't bother removing apps, I just move them to other screen-pages that I don't look at. Consequently I have a 'first-screen' that has only about half-a-dozen apps showing. *
If I can be bothered and have some time to kill, I might actually remove some apps from the phone, but generally I can't be bothered.

* It's not a huge list.
On the bottom row: phone, texts, camera
On the main screen: Settings, clock (alarms,reminders), browser, photos, calendar, notes.
