For a small tool site, would you avoid client-side rendering for SEO pages?

I’m building a small tools/content site and trying to keep the public pages SEO-friendly from the start.

The actual tools can be interactive, but I’m wondering about the surrounding pages: homepage, tool landing pages, category pages, docs/help pages, etc.

My instinct is to make those pages mostly static or server-rendered, with normal HTML content available without waiting for JS. Then only use client-side rendering for the actual interactive parts.

For people who build small sites that need organic traffic, is this still the safest approach?

Or is modern Google rendering good enough that CSR is usually fine as long as the site is fast and internally linked well?
