wix is a content management system (CMS) i believe, but you wont be able to dig into it and customize functionality (to add new features). The others i have no experience in, but they look like screen layout / mockup tools.. not actually frameworks to build a product.

is your "mvp" going to be an offline business that just needs a website? Wix would be okay i guess. If you want to build a product, then i suspect that these won't be enough for your needs.
