Until recently (moved to GrapheneOS) I ran stock Android for years and never had an issue with turning any notifications from default apps. Maybe this is different with other manufactures and custom OS version (e.g., Samsung's)? I think the only thing that bugged me was Google Play pushing new features/ways to give them money, but that was only within the app itself when I opened it. Notifications of that sort were all easily blocked. The only notifications I got and get are ones I want (99% of it are messages from messaging apps, calendar reminders, and alarms).
