Guys on android... would you not consider Youtube Revanced ? It involves downloading the original Youtube android app and then 'patching' (built in automatically) all the junk, tracking and ads infested within the app and lets you install what is a premium version of YT with login available. Not sure if there is an alternative available for Apple devices but for android TV as one of the other guys mentioned Smart tube and newpipe are also good for adfree, the latter a bit of a pain setting up account.
