My use case:

I would like to create a unique textfield per region in a custom form.

MYMODULE/MYMODULE.module:

function MYMODULE_preprocess_region(&$variables) 

 foreach (array($variables['elements']['#region']) as $key) 
 drupal_set_message($key);
 

MYMODULE/src/form/MyModuleForm.php:

protected function getEditableConfigNames() 
 return [
 'module_config.module_config_settings',
 ];


public function buildForm(array $form, FormStateInterface $form_state) 

 $config = $this->config('module_config.module_config_settings');

 //build this...
 $form['region_name'] = array(
 '#type' => 'textfield',
 '#title' => t('Form Item Title),
 );

 return parent::buildForm($form, $form_state);

What is the appropriate way to pass variables/info from the .module file to the .form?

*Note: I have a fully functioning form, hopefully I am showing enough of it to illustrate my focus.

It seems that you can get the list of blocks from this answer: How do i get the all the regions available in the current theme programatically?

MYMODULE/src/form/MyModuleForm.php:

protected function getEditableConfigNames() 
 return [
 'module_config.module_config_settings',
 ];


public function buildForm(array $form, FormStateInterface $form_state) 

 // Get the block list based on previous Q/A
 $theme = Drupal::theme()->getActiveTheme()->getName();
 $system_region = system_region_list($theme, REGIONS_ALL);

 foreach ($system_region as $region) 
 $form[$region . '_title'] = [
 '#type' => 'textfield',
 '#title' => t('Form ' . $region . ' Title'),
 ];
 

 return parent::buildForm($form, $form_state);

You try the code

function MYMODULE_preprocess_region(&$variables) 
 $regions=;
 foreach (array($variables['elements']['#region']) as $key) 
 $regions =$key;
 
$config = Drupal::service('config.factory')->getEditable('module_config.module_config_settings');
$config->set('config_regions', $regions);
$config->save();

call config:

$config = $this->config('module_config.module_config_settings');
$config->get('config_regions');
