There is a half way step (on Android at least, I assume Apple has similar) you can set "Do Not Disturb" and then white list the people who can message/call through the "Do Not Disturb" so you are reachable but only by people you trust/want to be able to reach you.

I just didn't use one, I have a rough rule that introducing new technology into my life has to be a complete and obvious unalloyed win or I just don't, it's a very high bar for a new technology to clear but it also means I don't spend money on things that end up in drawers because they either turned out not to meet the hype or just annoyed the living hell out of me after the initial "oooh shiny" wore off.

I do the Do Not Disturb + whitelist thing on my iPhone.

I also disable any and all notifications of apps other than direct messaging apps. No group message notifications.

I’ve been 24/7 do-not-disturb mode with all notifications disabled, for the past 10 years. It’s been wonderful for “intentionality” and agency over my time. I use my phone when I want to do something on it, not when the phone beeps and buzzes telling me to use it.

I don’t even whitelist anyone anymore. If it’s important they will leave a message and I’ll get back to them.

I can't really do that. For some things (urgent and important), loved ones need to be able to reach me.

But yes, a lot of this advice would work.

You have to remember that not that long ago it was simply impossible to reach most people who were not at home or at work. Because it was impossible, nobody felt slighted that you were unable to read their message or take their call immediately. And nobody felt any anxiety about leaving the house for a few hours to shop or go to a movie or a ball game and being unreachable. Loved ones managed and life went on.
