The benefit is independence: you can publish a blog post or change a price without calling a developer. The cost is that a CMS adds complexity, needs updates for security, and can be slower or more rigid than a purpose-built site.
If your content rarely changes, a CMS may be unnecessary overhead. If you publish regularly or many people contribute, a CMS pays for itself. Headless setups give editors a CMS while developers keep full control of the front end, which is a common modern middle ground.
