I almost went down that route when it came time to upgrade a few months back. Ultimately though, my lifestyle is dependent on having a smartphone. It’s just more convenient to have a wallet of virtual cards on my phone, GPS is right there without needing a second device. If I had gone for a dumbphone, I’d have essentially been delegating any smartphone requirements to my wife.
Ended up just going for a 13 Mini, figuring that the smaller screen might make me less inclined to waste so much time online. It’s partially worked.
