Answer 1

The value will be save in this pattern:

section_id/group_id/field_id

Sot the identifier for any of the filed will follow this pattern

For direct query in your database you can use:

select * from core_config_data where path='*section_id/group_id/field_id'

In your case query will be:

select * from core_config_data where path='vsbridge_indexer_settings/catalog_settings/product_attributes'

On code level you need to follow this to fetch your data using this:

protected $scopeConfig;

public function __construct(
    ...
    \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
    ...
)
{
    ...
    $this->scopeConfig = $scopeConfig;
    ...
}

public function yourFunction()
{
    $productAttributesConfig = $this->scopeConfig->getValue("vsbridge_indexer_settings/catalog_settings/product_attributes");
}
