Hi @grid7,
WIX is for Non-Non-non-non developers :D, WordPress and/or Webflow are good solutions.
I am actually a WordPress developer and made a plugin that creates custom post types via external sources. Let me know when your WordPress site is up and running and I can give you a Beta access for you to test the plugin. I did make real time CPT creation but that can be developed. My website with a live demo is almost ready.
