Thanks @hube2 for your quick answer! Actually, I was counting on you 😉

With the field setting I meant a field setting for the acf-field-group-edit-screen:

add_action("acf/render_field_settings/type=text", [$this, 'render_field_settings'], 9);

The setting:

/**
 * Render field settings for multilingual fields
 *
 * @param Array $field
 * @return void
 */
public function render_field_settings( $field ) {

  acf_render_field_setting( $field, array(
    'label'         => __('Multilingual?'),
    'instructions'	=> '',
    'name'          => 'acfml_multilingual',
    'type'          => 'true_false',
    'ui'            => 1,
  ), false);

}

On the second try, it seems like I made it work. The solution was to hook into acf/update_value *after* the ACF hook (I used a priority of 12):

add_filter("acf/format_value/type=group", [$this, 'format_multilingual_value'], 12, 3);

My update_value-function:

/**
 * Write the default language's $value to the group $value itself
 *
 * @param mixed $value
 * @param int $post_id
 * @param array $field
 * @return mixed
 */
public function update_multilingual_value( $value, $post_id, $field ) {
  if( !$this->is_acfml_group($field) ) return $value;
  $default_language = acfml()->get_default_language();
  $value = get_field("{$field['name']}_$default_language", $post_id, false);
  return $value;
}
