I think web components would be an excellent pairing with htmx. You get some kind of component abstraction (admittedly janky in some ways, though libraries like lit or atomico make this much better). But crucially you get automatic upgrade/initialize behaviour whenever the browser encounters a custom element. So the backend can just send down the custom elements as plain html, you don't need to wire anything up, the browser will bring them to life.
