One option if you want only one phone, is to set up a separate profile that only includes certain things. Or even a notification scheme on the main profile that only lets one or two people get notifications through. The family messaging app might get mixed up if it's not synced on your main phone, if people don't know when to message you where. Signal's notification settings and tabs can be handy - you just can't use one number on two phones at once. But to your question, I'd find something for music or audiobooks. Maybe recipes, if cooking helps you unwind. I like CoMaps lately. Weawow is nice for weather.
