Under European law, Wix HAS to offer a data export tool. I mean it may not be usable to rebuild a website quickly, but at least you should be able to get your content out in some format or other.

If however your customers are natural persons, you can migrate their data from a competitor (with their help and/or agreement).
Helping with the latter appears to be the point of Hotswap.
Exactly. Content in your website is not information relating to an identified or identifiable natural person. GDPR does not require a company to provide export of website content. It does have a requirement to export data they have stored about you though.
(Not disputing your assessment myself)
