It's a very bad idea if you want to use the account as a Google account. i.e. smart home does not work, lots of user features do not work, there is no workaround to this other than "don't use a Google Workplace account for personal life things, get a Gmail account".
When I was admining G Suite, if you wanted to call in, you needed to login to get the phone number and an access code. Which is hard to do when you can't log in.
