I'm with you. As I mentioned elsewhere, I'd have a Light Phone if it could use Telegram and a few other "essentials." Throw in a good camera and it'd be incredible.
At the moment I use greyscale mode on my Pixel and have uninstalled apps, only using them in the browser if I "need to." It's not much, but adding that small friction helps somewhat.
Some more friction, use a password manager and change the password to a really long string of characters, then don't install the password manager on the phone.
