Answer 1

By making the setting stores>configuration>catalog>inventory> Display Out of Stock Products to 'No' out of products will not visible at frontend. But it seems that in your featured block you have get the collection of product using incorrect code. Use below code which returns only In Stock products collection-

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$productCollectionFactory = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');

$productCollection = $productCollectionFactory->create() ->addAttributeToSelect('*') ->addAttributeToSort('created_at', 'DESC') ->joinField('stock_item', 'cataloginventory_stock_item', 'qty', 'product_id=entity_id', 'is_in_stock=1') ->setPageSize(8)->load();
