I agree. I feel like in my decade or so of professional experience, server-side rendering has made sense a handful of times and client-side rendering has made sense a handful of times. As you're saying: each tool comes with its own strengths and weaknesses and you should really just aim to understand the use case for each so you know when to apply them, rather than look for some one-sentence dogma about which thing is the devil to recite back to yourself when presented with a choice.
