You can create a Block class and inject Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory in the constructor and you can get/display product collection in phtml file.

Check below code:

<?php
namespace Vendor\Module\Block;

class ProductDisplay extends \Magento\Framework\View\Element\Template
{    
    protected $_productCollectionFactory;

    public function __construct(
        \Magento\Backend\Block\Template\Context $context,        
        \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,        
        array $data = []
    )
    {    
        $this->_productCollectionFactory = $productCollectionFactory;    
        parent::__construct($context, $data);
    }

    public function getProductCollection()
    {
        $collection = $this->_productCollectionFactory->create();
        $collection->addAttributeToSelect('*');
        $collection->setPageSize(5); // fetching only 3 products
        $colletion->setOrder('created_at','DESC'); //sort by date created 
        return $collection;
    }
}  

In your phtml file:

$productCollection = $block->getProductCollection();
foreach ($productCollection as $product) {
    print_r($product->getData());     
    echo "<br>";
}
