How do I get current category "page_layout" value? e.g "1 column" or "2 column" and so on. The values from Layout screen shoot bellow.

You can inject BuilderInterface to your constructor

public function __construct(
 MagentoFrameworkViewModelPageLayoutConfigBuilderInterface $pageLayoutBuilder
 ) 
 $this->pageLayoutBuilder = $pageLayoutBuilder;


public function getLayouts() 
 $pageLayout = [];
 $pageLayout = $this->pageLayoutBuilder->getPageLayoutsConfig()->toOptionArray(); 
 unset($pageLayout[0]);
 return $pageLayout;

You need to create observer and inject MagentoFrameworkAppRequestHttp into the constructor

public function __construct(
 ...
 MagentoFrameworkAppRequestHttp $request
) 
 ...
 $this->_request = $request;


public function addCatalogToTopmenuItems(MagentoFrameworkEventObserver $observer)

 $full_action_name = $this->_request->getFullActionName();
 $layout = $observer->getEvent()->getLayout(); //Return layout name

I wanted to achieve the exact same thing. I ended up creating a helper class that injects both MagentoFrameworkViewResultPage and MagentoFrameworkViewLayout.

The Page object can retrieve the selected layout using the method named getConfig()->getPageLayout(). But this method will return NULL if the page layout has not been selected in the admin area. So I ended up adding a custom method that will return the default page layout if no layout has been selected.

Helper class example

<?php

namespace VendorNameModuleNameHelper;

use MagentoFrameworkAppHelperAbstractHelper;

class Data extends AbstractHelper


 /**
 * @var MagentoFrameworkViewResultPage
 */
 protected $_pageResult;

 /**
 * @var MagentoFrameworkViewLayout
 */
 protected $_layout;

 public function __construct(
 MagentoFrameworkAppHelperContext $context,
 MagentoFrameworkViewLayout $layout,
 MagentoFrameworkViewResultPage $pageResult)
 
 $this->_pageResult = $pageResult;
 $this->_layout = $layout;

 parent::__construct($context);
 

 /**
 * Will return the currect page layout.
 *
 * @return string The current page layout.
 */
 public function getCurrentPageLayout()
 
 $currentPageLayout = $this->_pageResult->getConfig()->getPageLayout();

 if (is_null($currentPageLayout))
 
 return $this->_layout->getUpdate()->getPageLayout();
 

 return $currentPageLayout;
 

Template file usage

<?php

$data = $this->helper('VendorNameModuleNameHelperData');

echo '<pre> Page Layout:' , $data->getCurrentPageLayout(), '</pre>';

This might not be the best way to achieve this, but with Magento2's lack of documentation for developers, this is the only solution I could find that works in later versions of Magento2. I hope this helps!
