one underrated approach more and more people are finding success with: apple watch ultra as a primary device (optionally with a case for a more phone-like factor)

you can do most things an iphone does, but you can't doom scroll. you don't have to eject out of apple ecosystem, you get payments, 2fa, navigation, notifications. your iphone can remain as a backup that's always in sync for when you need it (e.g. traveling)
