It’s a ridiculous pain in the ass made tolerable because we’re both tech industry dinosaurs. Initially it was the only way to get TOTP 2FA on a Gmail account which is why I switched and because of the way Google does Google things my spouse has a completely separate account (she was a Googler at the time though has now successfully escaped). For my MIL we set up G Suite because it was the easiest way to lock down her security settings and support her remotely. There is no G Suite “family” option, you’re either a business or an enterprise.

For our purposes it’s been fine, but it’s overkill for the typical family or typical consumer.

One definite downside is that G Suite accounts are not considered to be consumer accounts so you run into various Google services which either don’t work at all or work very differently. For the brief time we used Google Home it could not access either of our G Suite calendars (but somehow the Alexa could). Our Nest footprint exists in a separate world from our G Suite accounts. When we had YoutubeTV we had to use a separate GMail account because (at the time, I don’t know if this is still the case) …because G Suite accounts could not be used for YouTube TV.
