Maybe you know that I have an account at ArtStation where I’m showing/selling my projects and products too.
Last times I’ve seen more and more panorama images for archviz there, and I had to try this sort of presentation too.
In Blender it is really easy to setup: make a scene that is convenient for an all around render e.g. a room or interior, create a camera in the middle of this scene, set the lens type to “Panoramic” and the Panorama Type to “Equirectangular”, set the dimensions resolution to a ratio of 2:1 and then hit render and save this render as a jpg.
You have to upload this image as “360 Pano” in ArtStation and after publishing it you can easily navigate through the image like in this one.
