Answer 1

There is no need to pass docx file extension to <item name="image_allowed" xsi:type="array"> and <item name="media_allowed" xsi:type="array"> try with below way it's working for me in Magento 2.3.1.

app/code/[Company]/[Module]/etc/di.xml

Add below code.

<type name="Magento\Cms\Model\Wysiwyg\Images\Storage">
        <arguments>
            <argument name="extensions" xsi:type="array">
                <item name="allowed" xsi:type="array">
                    <item name="docx" xsi:type="number">1</item>
                    <item name="pdf" xsi:type="number">1</item>
                </item>
            </argument>
        </arguments>
    </type>
    <preference for="Magento\Cms\Model\Wysiwyg\Images\Storage" type="[Company]\[Module]\Model\Cms\Wysiwyg\Images\Storage" />

create Storage.php file at below path.

app/code/[Company]/[Module]/Model/Cms/Wysiwyg/Images/Storage.php

    <?php

namespace [Company]\[Module]\Model\Cms\Wysiwyg\Images;

class Storage extends \Magento\Cms\Model\Wysiwyg\Images\Storage
{
    public function uploadFile($targetPath, $type = null)
    {
        /** @var \Magento\MediaStorage\Model\File\Uploader $uploader */
        $uploader = $this->_uploaderFactory->create(['fileId' => 'image']);
        $allowed = $this->getAllowedExtensions($type);
        if ($allowed) {
            $uploader->setAllowedExtensions($allowed);
        }
        $uploader->setAllowRenameFiles(true);
        $uploader->setFilesDispersion(false);
        $result = $uploader->save($targetPath);

        if (!$result) {
            throw new \Magento\Framework\Exception\LocalizedException(__('We can\'t upload the file right now.'));
        }

        // Change Start
        if (strtolower($uploader->getFileExtension()) !== 'docx' && strtolower($uploader->getFileExtension()) !== 'pdf') {
            // Create Thumbnail
            $this->resizeFile($targetPath . '/' . $uploader->getUploadedFileName(), true);
        }

        $result['cookie'] = [
            'name' => $this->getSession()->getName(),
            'value' => $this->getSession()->getSessionId(),
            'lifetime' => $this->getSession()->getCookieLifetime(),
            'path' => $this->getSession()->getCookiePath(),
            'domain' => $this->getSession()->getCookieDomain(),
        ];

        return $result;
    }
}

Run php bin/magento cache:clean

Then Go to Admin > Content > Page > Edit or Add new page Inside content click on insert image and upload docx file

I hope it helps!

Please Look at here,

Please change this file

Add any extension you want to add <item name="docx" xsi:type="number">1</item>

<argument name="extensions" xsi:type="array">
<item name="allowed" xsi:type="array">
