How do I organize notifications on a Galaxy Note 10 - Separate Messages from System Nots, Different Sounds, etc

Just switched from iPhone to my Note10 and I love it. However what drives me crazy is that I get tons of system notifications that all pool in the Notification bar. However, to be honest I only really want to see personal notifications there, like messages and so on, System Notifications better only if I request to see them. How do I separate system notifications and message notifications? Also how do I specify different sounds, so I hear if it's a WhatsApp or Insta or Facebook ... Also, how do I make these notifications appear on the locked screen, like they do on the iPhone?
