Here is what I come up with based on your suggestion:

    function my_save_json( $path ) {

        if( isset($_POST['acf_field_group']['key']) ) {

            $paths = my_load_json(array()); //  pass in empty array to only get local paths

            foreach( $paths as $load_path ) {

                //  loop over each load path for json files
                foreach (glob($load_path . "/*.json") as $filename) {
                    
                    $field_group = json_decode(file_get_contents($filename), true);
                    
                    //  if the key matches a group in this plugin then return the path
                    if (is_array($field_group) && $field_group['key'] == $_POST['acf_field_group']['key']) {
                        return $load_path;
                    }
                }

            }

        }

        // return
        return $path;

    }

    function my_load_json( $paths ) {
        $paths[] = MY_PLUGIN_DIR .'fields';
        return $paths;
    }

This works on next field group save if I move the generated JSON file into my plugin directory.

How does that look to you?
