In Drupal 8, field_info_field() has been deprecated.
I tried using \Drupal\field\Field::fieldInfo()->getField('field_address') and
\Field::fieldInfo()->getField('field_address'), but I get this error.
Fatal error: Class 'Drupal\field\Field' not found in /var/www/drupal/modules/custom/foo/src/Controller/FooController.php
What am I missing?
According to the change record:
field_info_field($entity_type, $field_name) -> FieldStorageConfig::loadByName($entity_type, $field_name)
So you should use \Drupal\field\Entity\FieldStorageConfig::loadByName from now on.
It's probably best to use change records and issues on Drupal.org itself for docs at the moment, rather than 3rd party websites - I think they have slightly more chance of being right and kept up to date when something changes.
\Drupal\field\Entity\FieldStorageConfig::loadByName('node', 'field_address') is always empty for me. I dug into how loadByName works, and was able to extract the desired results by making this call: \Drupal::config('field.storage.node.field_address')->get()

loadByName() in my previous comment correct? I've since removed the address module and then tried with a core field, that returns null as well.

Use this :
use Drupal\field\Entity\FieldStorageConfig;
$field = FieldStorageConfig::loadByName('node', $field_name);
$allowed_values = options_allowed_values($field);
For those looking for a D10 answer:
/** @var \Drupal\field\FieldStorageConfigInterface $field_config */
$field_config = \Drupal::entityTypeManager()
->getStorage('field_storage_config')
->load(implode('.', [$entity_type, $entity_bundle, $field]));
