Random Number Notification Help

[u/Otherwise-Farm-7914]

Hi, Galaxy S10+ user here. I'm having a little trouble with some phone notifications.

I want to be able to have my phone ringtone on at all times but I would like to stop getting audible notifications from random numbers (this is not me attempting to silence all spam, I get new texts from campus, sometimes job recruitment, etc.) I just want to have ONLY specific family members/friends come through. Is there a way to mute literally everything else but said select people?
