You can always pay for managed versions of these services if you want the piece of mind. NextCloud and email providers come to mind. Other than that, Docker has simplified things a lot in the self-hosting space. It's not quite as plug-and-play as Lego bricks yet, but it's made experimentation and sustainable self-hosting much easier as long as you're running on a supported platform. It's much easier to version the environment, much easier to keep the application runtime configuration clean, and much easier to move service instances across machines if you're too small to invest time in orchestration like K8s.
