I don't turn my WiFi off, but I leave my phone on focus mode, which disables notifications for certain apps for a certain period of time you set. I set a schedule to turn on focus mode every night 10.30, so that I stop checking my phone, and to automatically turn back on at 8.30 in the morning after I'm done with all my morning routines. But phone calls can still come through no problem just in case there's an emergency.

I think it is a good idea. I do the same, because I need to use my phone as an alarm clock right on my desk near my bed, so I just switch off the WiFi connection.
