Need for Experimenting with Astra and Hello Themes
There wasn’t a specific need to change themes, but as an enthusiast, I wanted to check the compatibility of these themes with the new version of ClassicPress, having previously tested out the Astra theme in 2021. The process involved creating child themes for each and customizing functions.php, footer.php, and style.css files to suit my needs.
I also tested the default ClassicPress theme, as well as Astra, Hello and GeneratePress themes from WordPress.org.

Conclusion
Both Hello and Astra themes worked well with ClassicPress, eliminating the need for blocks, as well as Elementor or any other page builder. Using LLM tools, I was able to achieve a variety of styling and functionality. Plugins, of course, would make the customization and user experience even better. This exploration further solidifies ClassicPress as a versatile platform for website building and customization.
