Firstly, you can use ObjectManager:

Get custom options of products present in shopping cart

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$cart = $objectManager->get('\Magento\Checkout\Model\Cart'); 
 
// get cart items
$items = $cart->getItems();
 
// get custom options value of cart items
foreach ($items as $item) {
    $options = $item->getProduct()->getTypeInstance(true)->getOrderOptions($item->getProduct());
    $customOptions = $options['options'];
    if (!empty($customOptions)) {
        foreach ($customOptions as $option) {
            $optionTitle = $option['label'];
            $optionId = $option['option_id'];
            $optionType = $option['type'];
            $optionValue = $option['value'];
        }
    }
}

Retrieve custom options of products present any order

$orderObject = $objectManager->get('\Magento\Sales\Model\Order'); 
 
// load by order id
$orderId = 1; // YOUR ORDER ID
$order = $orderObject->load($orderId);
 
// load by order increment id
// $incrementId = '000000001'; // YOUR ORDER INCREMENT ID
// $order = $orderObject->loadByIncrementId($incrementId);
 
$items = $order->getAllVisibleItems(); // get all items aren't marked as deleted and that do not have parent item; for e.g. here associated simple products of a configurable products are not fetched
 
// Order items can also be fetched with the following functions
// $items = $order->getAllItems(); // get all items that are not marked as deleted
// $items = $order->getItems(); // get all items
 
foreach ($items as $item) {
    $options = $item->getProductOptions();        
    if (isset($options['options']) && !empty($options['options'])) {        
        foreach ($options['options'] as $option) {
            echo 'Title: ' . $option['label'] . '<br />';
            echo 'ID: ' . $option['option_id'] . '<br />';
            echo 'Type: ' . $option['option_type'] . '<br />';
            echo 'Value: ' . $option['option_value'] . '<br />' . '<br />';
        }
    }
}

However, using ObjectManager directly for that is not the great solution. You can still use the code with dependency injection as the below:

Open the block class Mageplaza_HelloWorld, then inject the object of \Magento\Sales\Model\Order in the constructor of my module’s block class.

app/code/Mageplaza/HelloWorld/Block/HelloWorld.php

<?php
namespace Mageplaza\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
    protected $_orderModel;    
    
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,
        \Magento\Sales\Model\Order $orderModel,
        array $data = []
        )
        {        
            $this->_orderModel = $orderModel;
            parent::__construct($context, $data);
        }
    
        public function getOrderItems($orderId) 
        {
            $order = $this->_orderModel->load($orderId);
            return $order->getAllVisibleItems();        
        }
}
?>

Like that, you can use the function in the .phtml file.

$orderId = 1; // YOUR ORDER ID
$items = $block->getOrderItems($orderId);
 
foreach ($items as $item) {
    $options = $item->getProductOptions();        
    if (isset($options['options']) && !empty($options['options'])) {        
        foreach ($options['options'] as $option) {
            echo 'Title: ' . $option['label'] . '<br />';
            echo 'ID: ' . $option['option_id'] . '<br />';
            echo 'Type: ' . $option['option_type'] . '<br />';
            echo 'Value: ' . $option['option_value'] . '<br />' . '<br />';
        }
    }
}
