Answer 2

You can use a logger to debug cron.

If you are using logger for only testing purpose, you can use direct code either use proper magento standard

With Magento 2.4.4 & plus versions use below code:

$writer = new \Zend_Log_Writer_Stream(BP . '/var/log/testing.log');
$logger = new \Zend_Log();
$logger->addWriter($writer);
$logger->info('Test the log');
$logger->info(var_dump($yourVariable));

For Magento 2.4.2 & lower versions:

$writer = new \Zend\Log\Writer\Stream(BP . '/var/log/custom.log');
$logger = new \Zend\Log\Logger();
$logger->addWriter($writer);
$logger->info('Custom message'); 
$logger->info(var_dump($yourVariable));

UPDATE:

Try below:

As mentioned by MagePal Extensions in your comment.

Create a new file, for example, test.php, and put it in your magento2 pub directory with the following code:

You have to replace NameSpace\YourClassName with your cron class. And then hit this file in browser to debug the code for cron. Your cron will execute by hitting this file on browser.

<?php
require __DIR__ . '/../app/bootstrap.php';

class TestMyClass
    extends \Magento\Framework\App\Http
    implements \Magento\Framework\AppInterface
{
    public function launch()
    {
        $this->_state->setAreaCode(\Magento\Framework\App\Area::AREA_ADMINHTML);
        $myClass = $this->_objectManager->create('NameSpace\YourClassName');
        $myClass->execute(); // In cron jobs we usually use the execute() method as the entry point
        return $this->_response;
    }
}

$bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $_SERVER);
/** @var \Magento\Framework\App\Http $app */
$app = $bootstrap->createApplication('TestMyClass');
$bootstrap->run($app);
