I will probably get downvoted as I am in minority who still believe Server Side Rendering is the best approach for most of the web with exceptions to some websites that require Single Page App functionality.

I still think web would be best if you do SSR and then replace HTML DOM elements using frameworks like Stimulus Reflex or Hotwire. For millisecond interactivity you may want to write JS in a framework like Stimulus JS is good enough. Personally I do not see why everyone wants to build a Single Page App when 80% of your pages are static and can be server rendered and with SSR frameworks you can build something a lot faster than building a Frontend and Backend separately and fragmenting or hiring extra developers when it is not needed.

DHH said your code reflect your org structure and I agree companies that use SPA and Backends micro service arch usually tend to require more developers rather than companies that use SSR monoliths which appeal to smaller 1-3 developer companies that are building out a POC before committing huge amount of venture capital or their own money behind an idea that may not succeed.
