$objectManager = \Magento\Framework\App\ObjectManager::getInstance();  
$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToSelect('*')
$collection->addStoreFilter($storeid)
$collection->addAttributeToFilter('attribute_code');

use Magento\Framework\Data\OptionSourceInterface;
class Productlist implements OptionSourceInterface{
    /**
    * Get products
    *
    * @return array
    */
    public function toOptionArray(){
        $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
        $store=$objectManager->create('\Magento\Store\Model\StoreRepository');
        $productCollectionFactory =$objectManager->create('\Magento\Catalog\Model\Product')->getCollection();
        $storeId='3';
        $productCollectionFactory->addAttributeToSelect('name');
        $rootCategoryId = $store->getById($storeId)->getRootCategoryId();
        $productCollectionFactory->addAttributeToSelect('*');
        $productCollectionFactory->addCategoriesFilter(array('eq' => $rootCategoryId));
        $options = [];
        foreach ($productCollectionFactory as $product) {
            $options[] = ['label' => $product->getName(), 'value' => $product->getId()];
        }
        return $options;
    }
