Besides possible privacy issues one major problem with google accounts is that google doesn't work with "accounts". It works with "people" or "corporations". So if they think that corporate account X and private account Z are actually same person (decided by some obscure algo) they will link them in their DB and in case of any infraction, real or not, they will hellban both of them. And as we know there is no such thing as human support or appeal process with google. Don't use your private accounts anywhere where they might be linked, not even for password restore field. There are already enough horror stories about people losing gmails, youtube channels and so on, forever.
