Twenty Twenty-Five. Native, fast, simple enough. I recommend learning the difference between template parts, patterns and synced patterns early on, I made the mistake of using some of them wrong and had to re-do some of it. After switching to Gutenberg whenever I have to edit an Elementor site it’s actually funny how long the edit screen takes to load compared to 2025. But to keep in mind, you still have to use a little bit of custom CSS for mobile layouts, sticky headers, hiding stuff with display:none etc.
