My use case: I do static page generation with Elder JS and I need content creators to be able to contribute and edit content. ACF would be really practical to set up the data structures I need.
Otherwise use Strapi, Directus, or some other open-source headless CMS.
There's no reason to start a new project with WordPress today. It is a dumpster fire.
I had sworn off ever touching it again, but I inherited 5 sites with a new client, including one that was built very recently. All are on the latest minor version of PHP and WordPress with up-to-date plugins.
With all that out of the way...
WordPress makes it impossible to do even the most basic modern software development practices. You can't easily separate your data, config, content, design, and code.
It's all mixed together by default, and you'd have to essentially create external databases or repositories to accomplish that. There was a project to try to version WordPress with git and it was abandoned for being too complicated.
There are also a million ways to accomplish the same thing, to the point where it becomes nearly impossible to know if someone's code is stored in a theme file, plugin, or database string.
Having a healthy local/staging/production environment separation is nearly impossible, especially if you need your content people or front-end designers to be able to work in parallel with anyone maintaining WordPress.
Choosing WordPress for anything today is absolutely indefensible. It's old, messy, difficult to harden, expensive to host, unnecessarily complex, and (most importantly) superseded by much better tools that weren't written nearly 20 years ago.
