I do something similar with my phone. Android phone set to "do not disturb" permanently. The only exceptions calls/texts from starred contacts which include only my immediately family, work when I'm on call (and only then), and I'll temporarily add a starred contact if I'm expecting a call (eg I've called a tradesperson leaving a message and expect a call back). And even my immediate family talk to me primarily via chat apps that aren't covered via starred contacts. Therefore I know when my phone makes a sound it is something I need to respond to in a timely manner. Everything else causes a notifications pulse, with different colours for different apps (purple for a chat app, yellow for work email etc). It's so unobtrusive I don't notice it unless I deliberately look at it.
