Notifications are the soundtrack to modern digital life. When they're out of control, they make it hard to hear anything else going on... the payoff is worth it.
App developers want you to opt in to every notification possible, but thankfully, Android provides a lot of tools to help you tune in to the helpful stuff and tune out the distractions.
Starting with One UI 6.1, Samsung hid these options by default. Go to Settings > Notifications > Advanced settings > Manage notification categories for each app... an option to access Notification categories.
It's up to app developers to decide how to classify their notification channels. That's why you might see things you don't want (promotional notifications) bundled together with useful stuff, like order updates - thanks, Starbucks app.
