Website Design Recommendation

I recommend using a block theme, these are all free: https://www.ads-software.com/themes/tags/full-site-editing/

Block themes use the new Site Editor, meaning that how you can modify a theme is now almost limitless without even having to touch CSS: https://www.ads-software.com/documentation/article/site-editor/

There’s also a video tutorial if you prefer that style: https://learn.www.ads-software.com/tutorial/intro-to-the-site-editor-and-template-editor/

In particular, the new default theme, Twenty Twenty-Four, ships with a ton of pre-done templates to get you even closer to what you want before you start customizing it: https://www.ads-software.com/documentation/article/twenty-twenty-four/
