My guess (i dont understand it all that well) is that people are less again using systemd, than against a growing dependency on systemd. If something bad happens to it, it could drag down other big elements of the linux ecosystem with itself.

For furniture/house design, there is Sweet Home 3D. Otherwise, Blender can work for most of your desired features. Though both have 3D features that would be overkill, but they’re not that intensive for basic tasks as you ask.
