Contrary to common belief, WordPress nowadays is just as easy and accessible as Wix and Squarespace.  This is because WordPress prepared for innovation by allowing people to create plugins. A plugin like Elementor page builder offers the same drag-and-drop interface as Wix.
Setting up WordPress is slightly more technical, but the upside is that you are working with open-source software. When you work with Wix of SquareSpace, you are essentially ‘renting’  your data. With WordPress, you own all your data.
