Have you considered https://inertiajs.com? It's still SPA-ish, but keeps server-side routing and controllers. To me it sort of looks like templates rendered in the browser with almost no need to keep state and juggle xhr calls, the app component just re-renders with new props whenever something is submitted to the server.
"I'm burnt out on frontend frameworks. HTMX has been a good change to JS heavy alternatives."
"Can you give more thoughts on it for heavy interactions?"
"You might try LiveViewJS."
"Can you tell me about your experience with LiveViewJS?"
"Have you considered InertiaJS?"
I have no intent here other than I found this circular chain amusing. Let it go on long enough and someone will without a doubt recommend HTMX as if it's something they don't expect the parent has heard of.
