Some years age when I was still using some more google stuff (like an account for calling out from my PBX) I had each service assigned to its own google account to limit the impact of google doing something crazy to an account.

Apart from playstore youtube red is now the only service left - and that’s about to go as they now made it too expensive, especially taking into account that they enshittified it so much that we’ve blocked it on the TV, and “adfree on TV” was the main use case there…
