XF 2.0 How to get custom field value in PHP when it's from a set of choices

[XFConvert]

Have my own PHP script to authenticate an XF2 user and trying to get the custom profile fields, like "country". That profile field is from a set of choices. Here is how far I've gotten:

// bootstrap framework
$dir = __DIR__;
require($dir . '/src/XF.php');

XF::start($dir);

$app = \XF::setupApp('XF\App');

$username = "someuser";
$password = "somepassword"

$ip = $app->request->getIp();
$loginService = $app->service('XF:User\Login', $username, $ip);

$user = $loginService->validate($password, $error);

echo $user->Profile->custom_fields->country;

The output of $user->Profile->custom_fields->country is something like:

"united_states_2"

which is apparently some kind of reference to the actual string in the set of choices for that custom profile field.

Exactly how do I get the actual string value (which in this case should be "United States")?

Thanks in advance for any help!

$entityManager = \XF::app()->em();

/** @var \XF\Mvc\Entity\Finder $fieldFinder */
$fieldFinder = $em->getFinder('XF:UserField');

/* Get all user fields */
/** @var \XF\Mvc\Entity\ArrayCollection $allUserFields */
$allUserFields = $finder->fetch();

/* Get a set of user fields */
/** @var \XF\Mvc\Entity\ArrayCollection $userFields */
$userFields = $finder->where('field_id', '=', ['set', 'of', 'field', 'ids'])->fetch();

/* Get a single user field */
/** @var \XF\Entity\UserField $userField */
$userField = $finder->where('field_id', '=', 'country')->fetchOne();

After that match them against your user values to get the display values.

Thank you very much katsulynx, that was a huge help. I had to play around with it a bit but I got it working.

Now a related question if I may.

What would the template syntax be to do the same thing -- but in a thread post? Basically I want to add a custom field like "country" near the username on each post in a thread. (And again, the value for that custom field is from a set of choices like what I explained above.)
