You want to make a single action that takes a parameter, in this case,
your filename (or rather, a string URI).

static void
on_open_file (GSimpleAction *action,
              GVariant      *param,
              gpointer       user_data)
{
  const gchar *uri = g_variant_get_string (param);
  GFile *file = g_file_new_for_uri (uri);

  // ...
}

static const GActionEntry entries[] = {
  { "open-file", on_open_file, "s" },
};

and then where you call the action, use the detailed action name or
specify a target like:

  g_menu_item_set_action_and_target (menu_item, "prefix.open-file",
                                     "s", uri);

If you'd like a similar, rather complex example, check out how we open
files based on mime-types in Builder.
