Customer here. Here's how I handle notifications:

1) When I install an app, I give it all requested notification permissions.

2) When an app sends a poorly-timed notification, I add it to a notification profile that limits when notifications are shown. When an app sends me an annoying message (anything marketing-related, or anything that looks like it's intended to drive "engagement"), I disable all notifications for the app.

3) If the app is not usable with notifications disabled, I stop using the app. If the app is required by a service I use, then I cancel the service.
