That was very helpful, thank you - I didn't know all that, and even if I did, many others coming across this probably did not either.
I still don't feel like going traipsing around minefields. I'm sure there's a benefit from tying together all Google services - for me, it just keeps me away from most of them. And I even pay for Google One.
you would think that paying for it would translate into a slightly better level of customer care. But that doesn't seem to be the case with Google. I pay for YouTube premium and I had my fair share on unanswered issues. Not sure about the other services though, YouTube is the only Google product I still use and I have a separate account only for that. Hopefully Google One turns out to be better than YouTube Premium!
