The loading when going back is pretty annoying. If you're going to dynamically fetch things with JS, you should go fully SPA in my opinion and cache that stuff locally. So when I push back, it's instant. Or go full server-side rendering with caching, so when I press back, I get a quick 304 and it's _basically_ instant. Hitting the loading screen each time is really bad UX imo.
On a side note, is the data prepopulated by ChatGPT? I clicked on a few things and some of the ideas + comments look AI generated ;).
