Build or use a headless CMS for pure content management, have a preview build (client side rendered) of your site to see the changes instantly. Then trigger releases for optimized, static builds.
For me this is a quality improvement in terms of performance and security and a DX improvement in terms of extensibility and separation of concerns. But again, requires one to make a bunch of decisions and plumbing so everything plays nice and coherent.
Moreover, Nextjs's devs are increasingly ignoring that use case to the point where it is unclear if you'll hit a roadblock where you can't update anymore because the required amount of hacking is just too much to continue using it like that.
