Answer 1

Step 1 : Create

Vendor/Module/etc/frontend/events.xml

<?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="customer_login">
        <observer name="customer_login_observer" instance="Vendor\Module\Observer\CustomerLogin" />
    </event>

</config>

Step 2 :

Create Vendor/Module/Observer/CustomerLogin.php

<?php

namespace Vendor\Module\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class CustomerLogin implements ObserverInterface
{
    protected $_responseFactory;
    protected $_url;

    public function __construct(
        \Magento\Framework\View\Layout $layout,
        \Magento\Framework\App\ResponseFactory $responseFactory,
        \Magento\Framework\UrlInterface $url,
    )
    {   
        $this->_layout = $layout;
        $this->_responseFactory = $responseFactory;
        $this->_url = $url;
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        /*$resultRedirect = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);
        $resultRedirect->setUrl('checkout/cart');
        return $resultRedirect;*/
        $RedirectUrl = $this->_url->getUrl('checkout/cart');
        $this->_responseFactory->create()->setRedirect($RedirectUrl)->sendResponse();
        die();
    }
}

For customization after-login redirect you need to add after plugin on \Magento\Customer\Controller\Account\LoginPost::execute where you should check is customer logged in and create custom redirect result.

Example

public function afterExecute(LoginPost $subject, ResultInterface $result)
{
    $isCustomerLoggedIn = $this->httpContext->getValue(Context::CONTEXT_AUTH);
    if ($isCustomerLoggedIn) {
        $result = $this->resultRedirectFactory->create()
            ->setPath('checkout/cart');
    }

    return $result;
}

Create events.xml from Module/etc/frontend/ folder and paste it below code.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../lib/internal/Magento/Framework/Event/etc/events.xsd">

    <event name="customer_login">
        <observer name="custom_customer_login" instance="Theme\VendorName\Observer\RedirectCustomerToLoginAtObserver" />
    </event>

</config>

And create RedirectCustomerToLoginAtObserver.php file from Module/Observer folder and paste it below code.

<?php

namespace Theme\VendorName\Observer;

class RedirectCustomerToLoginAtObserver implements \Magento\Framework\Event\ObserverInterface
{
    /**
     * @var \Magento\Framework\App\ResponseInterface
     */
    protected $_response;

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

        /**
    * @param \Magento\Framework\UrlInterface $url
    * @param \Magento\Store\Model\StoreManagerInterface $storeManagerInterface
         */
    public function __construct
    (
        \Magento\Framework\UrlInterface $url,
        \Magento\Store\Model\StoreManagerInterface $storeManagerInterface
    ){
        $this->_storeManager = $storeManagerInterface;
        $this->_url = $url;
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $storeObj = $this->_storeManager->getStore(1);
        $BaseURL = $storeObj->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_WEB);
        $url = $BaseURL . 'customer/account/login';
        $this->_response->setRedirect($url)->sendResponse();
    }
}

Feel free to ask if any.
