It is fairly easy to get started with, but has a lot of advanced features. You have all basic shapes, polygons, line and fill styles, basic text, layers, effects like ...

Honestly, your example illustrations were all top-down vector graphics, such as can be done in Adobe Illustrator, Affinity Designer, or InkScape or Xara. I don't think you need full-on 3D modeling, though if you do, Blender is a really great tool as mentioned before by @Steve Barnes. I fully second his recommendation.

I have often coded similar programs to generate the ...

You could almost certainly produce your display with python, ipython notebooks, (Jupyter), and bokeh, your notebook can poll the data from any suitable locations and could be viewed either via nbviewer as a static page or as a dynamic page.

I've used LibreOffice Impress as well as regular Powerpoint, where we've made stick templates of the appropriate size and orientation for students to put content into. This then gets output as PDF for the printers. Preparing the generic PPT is an effort but the consistency of output is well worth it.
