class AppController extends Controller
{
public function initialize()
{
	・・・
        $obj = TableRegistry::get('モデル名(+s)');
        $変数名 = $obj->find('list',['valueField' => 'フィールド名'])->toArray();
	$this->set('文字列', $変数名);
	・・・
}

・view

debug($変数名);

■Componentを使う場合
・SearchComponent.php
ドキュメントルート > src > Controller > Component > SearchComponent.php(作成)

namespace App\Controller\Component;
use Cake\Controller\Component;

class SearchComponent extends Component {

	public function search() {
		$cities = TableRegistry::get('Model名');
		$cities = $cities->find('list',['valueField' => 'フィールド名'])->toArray();
		return $cities;
	}
}

・controller

{
	// コンポート名
	public $components = ['Search'];
