You can export to mobile and desktop targets. For consoles, you are looking at a publisher or someone to do the porting process. Ratalaika games have ported Stencyl games to Switch, for example.
itch.io is a popular destination for uploading your HTML5 games, so consider uploading there. I don't know what will become of the Stencyl Arcade in the future, but for now there's not much use in uploading games there, since the upload is on Flash and not HTML5.
