web.php

Route::resource('/products', 'ProductsController');

Route::resource('/layouts/index', 'FeaturedController@index');  

Answer 1

as u r using data in layout u should use laravel view composer to share data to layout file ref link https://laravel.com/docs/7.x/views#view-composers

in your AppServiceProvider.php

inside boot() add this line

 public function boot()
    {
       \View::composer('layouts.index', function ($view) { // here layout path u need to add
        $features = Feature::get();
         $view->with([
            'features'=>$features,
         ]);
});
}

It share data based on specif view file like here layouts.index data is send to this view so if u not send data from controller it will get data from view composer
