Doesn't menu File > Open File do what you request,
by default?  Likewise, other file operations, such
as File > Insert File, File > Save As, and File >
Open Directory.

On MS Windows, for example, this just uses the usual
Windows file selection dialog box.

This depends on the value of option `use-file-dialog',
but that's `t' by default (as is `use-dialog-box').

 "Non-nil means mouse commands use a file dialog to ask for files.
  This applies to commands from menus and tool bar buttons even when
  they are initiated from the keyboard.  If 'use-dialog-box' is nil,
  that disables the use of a file dialog, regardless of the value of
  this variable."
