Use YouTube revanced. It's an app that patches the official YouTube apk. Basically you provide the version of the apk it requires (the patcher will tell you), select which patches you want (you can put all of them and disable what you don't need in the settings later) and if will create a new apk without ads that you can install
Is there a wiki for the best way to block ads per device type?
I've figures it out on Fire Stick (I know) and Firefox but I have no experience installing android apps via root or developer mode.

For android use either YouTube revanced or newpipe.
Also there is the piracy megathread which will help you with that!
Also adblocking DNS server in your router, or PiHole
