How many ways are there to damp a string?

This is my current nightmare.  Other people might lie awake pondering car problems or how to avoid having to deal with the leaky roof but me, I try to wrap my head around how to damp guitar strings.  (Actually I worry about leaky roofs and strange noises in my car too, but that's beside the point).
I've been familiar with damping bass strings for a while - but now I'm looking at damping any open string, which means treble strings too.  It's proving something of a challenge, so I thought I'd sit down and list all the ways I know currently.

Bass strings thumb
- if the thumb is moving to the next highest string, then its pretty easy to touch the ringing string with the  thumb while playing the next  note.
- and if not adjacent, you can still use the side of the thumb to damp the bass strings though it involves moving your hand
- you can put your thumb back down on the note you just  played
- if you’re moving the other way, from eg D to E string, you can go back and damp with the thumb after playing the next note

Fingers
- If moving to the next lowest string, eg E to B string as you play the B string note  you can flatten the left hand finger so it touches the higher string
- with the right hand you can drop another finger onto the string, e.g. play B string note with m and simultaneously drop a onto the E...
- you can use fretted notes instead of open strings -
- you can place a left hand finger early onto a fret you will soon be playing
- I guess you could reach  over and stop a bass string with the left hand

I’m still experimenting with this stuff so I’m sure there are more ways to learn - and all I can say is that it makes it exponentially  harder to figure out which fingers to use! And that doesn’t even begin to address  the question of which notes - really- need to be stopped and which can  inoffensively ring over😳
