What did you find overly complicated about Wix compared to Squarespace? (I don't have a dog in either race... started with Squarespace, but clients found Wix easier to use over time. Maybe that balance has shifted again recently?)
Compared to Wordpress, though, either is much simpler because they're fundamentally site builders as opposed to CMSes. With Wordpress you really have to think about concepts like "schema" and try to understand posts vs pages vs comments, and it gets way more complicated once you start adding in page-builder plugins or ACF or SEO optimizers or performance enhancements... Wordpress is way more powerful (and thus complex, buggy, and expensive in dollars and time) than any of the "build your own website" services, Wix or Squarespace.
