Answer 1

In your Collection.php which you are using for the Grid add below function code

protected function _initSelect()
{
    parent::_initSelect();

    $this->getSelect()
        ->columns('eas.attribute_set_name')
        ->join(
            ['cpe' => $this->getTable('catalog_product_entity')],
            'main_table.sku = cpe.sku',
            []
        )->join(
            ['eas' => $this->getTable('eav_attribute_set')],
            'cpe.attribute_set_id = eas.attribute_set_id',
            []
        );
}

Not sure to really understand your issue. To give you a strict answer the attribute set is stored in the table eav_attribute_set where you can find the columns attribute_set_id and attribute_set_name

Now if what you try to do is add that value into a grid, we need more information and code about what you've done.
