In general, on the desktop we try to avoid making people type a command into a terminal to do something - precisely because of the problem you mention: what is the name of the command, and what are the options, etc. Clicking on a file will open it in the preferred application for that purpose.
If you absolutely insist on having those 'generic wrappers', you'll find that the xdg scripts (xdg-open, xdg-email, etc) come pretty close to what you describe.

I agree that we shouldn't make anyone type a command. I'm allowing for a more convenient way to for those users who do.

The Xdg-utils are great, but they aren't intended for end users to use to launch common applications. The Xdg-utils are meant to, in part, help applications open other applications. Since users don't ordinarily run the Xdg-util commands directly, it is okay that they are named xdg-whatever, instead of something more meaningful or intuitive. xdg-open "http://example.com/" is less intuitive than web-browser.
