I just assume you need to echo the product name only. If you need other fields, please let me know.

In your custom module PHP function:

protected $_quote;

public function __construct(
    \Magento\Quote\Model\QuoteFactory $quoteFactory
    /*Other DIs if you have*/
)
{
    $this->_quote= $quoteFactory;
    /*Other DIs  if you have*/
}

public function beforeSaveAddressInformation(
    \Magento\Checkout\Api\ShippingInformationManagementInterface $subject,
    $cartId,
    \Magento\Checkout\Api\Data\ShippingInformationInterface $addressInformation
){
    //Inside 
    $cart = $this->_quote->create()->get($cartId);
    $items = $cart->getAllVisibleItems();
    $result = [];
    if (count($items) > 0){
        foreach ($items as $item)
            $result[] = $item->getName();
    }
    return $result;
}
