"Business Starter" accounts are a different category of account that can't join or create a family (To share YouTube Premium, YouTube TV, etc). Also, if you stop paying your email account gets suspended.

Individual is a "normal" Google account and doesn't increase your storage from the default 15GB or support custom domains. But if you stop paying you still have a valid @gmail account and just lose access to the additional features.

"Business Starter" uses your own domain..."Custom email with your domain". So, yes, you would need to export the emails, but you retain your email address.
