Answer 1

Using Event observer to get estimated shipping address before place order. Please find below steps to get shipping address.

Step-1: Create custom Module

    Path- app/code/Custom/Module

Step-2: Create events.xml under module etc folder

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
   <event name="checkout_submit_before">
       <observer name="custom_module_observer_index" instance="Custom\Module\Observer\Index" />
   </event>
</config>

Step-3: Create Observer to execute event below path

    app/code/Custom/Module/Observer/Index.php

Index.php

<?php
namespace Custom\Module\Observer;
use \Magento\Framework\Event\ObserverInterface;
use \Magento\Framework\Event\Observer;
use Magento\Framework\App\Config\ScopeConfigInterface;
use Magento\Framework\Message\ManagerInterface;
use Magento\Framework\ObjectManagerInterface;
use \Magento\Checkout\Model\Session as CheckoutSession;

class Index implements ObserverInterface
{
     protected $messageManager;
     protected $scopeConfig;
     protected $checkoutSession;
     protected $logger;
   protected $_coreSession;
   protected $_customerRepositoryInterface;

     public function __construct(
        ManagerInterface $messageManager,
        ScopeConfigInterface $scopeConfig,
        ObjectManagerInterface $objectmanager,
        CheckoutSession $checkoutSession,
        \Psr\Log\LoggerInterface $logger,
     \Magento\Framework\Session\SessionManagerInterface $coreSession,
    \Magento\Customer\Api\CustomerRepositoryInterface $customerRepositoryInterface
                    ) {
        $this->messageManager = $messageManager;
        $this->scopeConfig = $scopeConfig;
        $this->_objectManager = $objectmanager;
        $this->checkoutSession = $checkoutSession;
        $this->logger = $logger;
        $this->_coreSession = $coreSession;
        $this->_customerRepositoryInterface = $customerRepositoryInterface;

    }
  public function execute(Observer $observer)
  { 



         $order = $observer->getEvent()->getOrder();
         $objectManager =  \Magento\Framework\App\ObjectManager::getInstance();        
         $storeManager = $objectManager->get('\Magento\Store\Model\StoreManagerInterface');
         $store_id = $storeManager->getStore()->getStoreId();
         $this->logger->info("storeid==>".$store_id."<");

         // get shipping address

         $shippingAddress = $order->getShippingAddress(); 
         $city = $shippingAddress->getCity();
         $country = $shippingAddress->getCountryId();
         $this->logger->info("shippingAddress=>".$country."<");
         $this->logger->info("shippingAddress=>".$city."<");

        } 


  }
