The biggest time saver will be not creating an SPA or creating an API. Just submit forms and return rendered HTML fragments if you need front end interactivity, and even then keep them to a minimum.

I've found alpineJS easy to learn but a good fit for this kind of approach.

Also, use a design system. I'm finding daisy UI a good mix between ease of use without a mess of tailwind classes, but you may prefer material etc.
