The primary reason I'd reach for the Jamstack over WordPress is security. A static website (relying on a headless CMS or a build/deploy process for content) is much more shelf stable than WordPress if the project isn't updated on a monthly basis. A lot of people have built successful businesses and sites with WordPress and continue to do so (this is what I got my start in consulting ten years ago). That said, WordPress provides a bigger surface area for vulnerabilities with the 3rd party plugin ecosystem and database connection compared to static sites. If you're familiar with it, and prepared to keep it up to date, it may be a good option for you. Otherwise, I'd go with the Jamstack (assuming it can handle whatever your use case is).
