Answer 1

You can use following code for return collection base on particular attribute, here $cb_city is a value based on which you want to filter-

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
 $prodCollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
 $collection = $prodCollection->create()
 ->addAttributeToSelect('*')
 ->addAttributeToFilter('cb_city',$cb_city)
 ->load();
 return $collection;

Answer 2

I got the collection with below script

 $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
 $productCollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
 $collection = $productCollection->create()
 ->addAttributeToSelect('*')
 ->load();
 echo "<pre>";
 print_r($collection->getData());
