As for portability, I'm not aware of the $EDITOR convention being

Can non-POSIX systems offer anything better? Any worthwhile

Yes. The one below is better.
ShellExecute(NULL, "edit", filename, NULL, NULL, SW_NORMAL);

For those not familiar with Windows, "edit" is not a command name, it's
an "object verb".  The above call invokes the user's configured command
to edit the specified file.  It might invoke a text editor for foo.txt,
an image editor for foo.png.  It's similar to right-clicking a file in
the file explorer and selecting "Edit".  Other verbs include "open",
"print", and "properties".

On Unix-like systems, xdg-open does something similar.  (It's typically
configured by default to invoke a GUI editor; it doesn't pay attention
to $EDITOR.)
