You can create a customer with order Id on checkout success

Use checkout_onepage_controller_success_action observer to create customer by order id. If customer email is already registered then, order assigned to the registered customer.

Here is the full module code for creating a new customer on order success. This module creates a new customer with order id. If customer already register, an order will be assigned to already register customer

1) Create registration.php

app/code/Myvendor/GuestRegistration/registration.php

<?php

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Myvendor_GuestRegistration',
    __DIR__
);

2) Create module.xml

app/code/Myvendor/GuestRegistration/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Myvendor_GuestRegistration" setup_version="1.0.0" />
</config>

3) Create events.xml

app/code/Vendor/GuestRegistration/etc/frontend/events.xml

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="checkout_onepage_controller_success_action">
        <observer name="myvendor_guestregistration_controller_success_action" instance="Myvendor\GuestRegistration\Observer\Convertguest" />
    </event>
</config>

4) Create Convertguest.php

app/code/Myvendor/GuestRegistration/Observer/Convertguest.php

<?php

namespace Myvendor\GuestRegistration\Observer;

class Convertguest implements \Magento\Framework\Event\ObserverInterface
{
    /**
     * @var \Magento\Sales\Model\OrderFactory
     */
    protected $_orderFactory;

    /**
     * @var \Magento\Sales\Api\OrderCustomerManagementInterface
     */
    protected $orderCustomerService;

    /**
     * @var \Magento\Store\Model\StoreManagerInterface
     */
    protected $_storeManager;

    /**
     * Convertguest constructor.
     * @param \Magento\Sales\Model\OrderFactory $orderFactory
     * @param \Magento\Sales\Api\OrderCustomerManagementInterface $orderCustomerService
     * @param \Magento\Customer\Model\CustomerFactory $customer
     * @param \Magento\Sales\Api\OrderRepositoryInterface $orderRepository
     * @param \Magento\Store\Model\StoreManagerInterface $storeManager
     */
    public function __construct(
        \Magento\Sales\Model\OrderFactory $orderFactory,
        \Magento\Sales\Api\OrderCustomerManagementInterface $orderCustomerService,
        \Magento\Customer\Model\CustomerFactory $customer,
        \Magento\Sales\Api\OrderRepositoryInterface $orderRepository,
        \Magento\Store\Model\StoreManagerInterface $storeManager
    ) {
        $this->_orderFactory = $orderFactory;
        $this->orderCustomerService = $orderCustomerService;
        $this->_customer = $customer;
        $this->orderRepository = $orderRepository;
        $this->_storeManager = $storeManager;
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $orderIds = $observer->getEvent()->getOrderIds();

        if (count($orderIds)) {
            $orderId = $orderIds[0];
            //You can also use checkoutSession to get last order  
            //$order = $this->_checkoutSession->getLastRealOrder();
            $order = $this->_orderFactory->create()->load($orderId);

            $customer= $this->_customer->create();
            $customer->setWebsiteId($this->_storeManager->getStore()->getWebsiteId());
            $customer->loadByEmail($order->getCustomerEmail());

            /*Convert guest to customer*/
            if ($order->getId() && !$customer->getId()) {
                /*New Customer*/
                $this->orderCustomerService->create($orderId);
            } else {
                /*Registered customer guest checkout*/
                $order->setCustomerId($customer->getId());
                $order->setCustomerIsGuest(0);
                $this->orderRepository->save($order);
            }
        }
    }
}

Now run following commands

php bin/magento setup:upgrade
php bin/magento setup:di:compile

Answer 2

Magento provides a better way to convert guest to the customer during checkout. When a user checkout as a guest, Magento shows an option to create an account after the checkout process completes.

When the user clicks on Create Account button, Magento uses the information provided by the customer during checkout, to create a new customer account and sends a link to set the password.

After setting up the password, the user can log in to the customer account in Magento website.

Please let me know if you still want to customize the checkout process like you have mentioned in the question.
