When I first got any modern Samsung phone, be it a flagship like my Z Flip 4 or a budget like any A-Series, they went [over the horizon notes] for ANY THING. Often about adding a Samsung Account, setting up your device, update notifications from Play/Galaxy Store, Cloud storage alerts, Dropbox promos, the whole nine yards. For someone coming over from Android 2.3, or the HTC Thunderbolt (remains my favorite phone, RIP and big middle fingers to the carriers for shutting down 3G) which ONLY went off for important stuff such as calls, texts, or emails, and gave far more control, modern phones tend to not allow the user to turn most of that nagware off.
There are apps such as Buzzkill that can clear 'un-clearable' notifications, which is great, but it's paid. Not a subscription thank goodness, but one time. I think $3.99.
Otherwise I keep DND (Do Not Disturb) on 24/7, exempting contacts for calls/messages. It's the closest I get to my Thunderbolt. Without it, I'd still be pulling 'weeds' as soon as I think I got all the useless notifications (and the sounds) finally done.
I started my smartphone journey with iPhone, and one of the main gripes I've always had with Android (even since the Thunderbolt/Android 2.3) is a 'messy status bar'. IMO the only things that belong up there are signal, battery status, network type, and time. I much prefer that any notifications are little red numerals on specific icons. That way I know which app has new alerts, and it doesn't trigger my OCD. I hate status bar clutter. It's even worse today.
