How to call static block from Category Layout Update XML Magento 2?

If you are using luma theme or any other, select the theme and save by below layout update. I used contact-us-info block for reference you can replace by your block id.

<referenceContainer name="content">
    <block class="Magento\Store\Block\Switcher" name="store_switcher" as="store_switcher" after="footer_links" template="switch/stores.phtml"/>

     <block class="Magento\Cms\Block\Block" name="test">
        <arguments>
            <argument name="block_id" xsi:type="string">contact-us-info</argument>
        </arguments>
    </block>
</referenceContainer>

Have added reference screen-shoot below.

<referenceContainer name="content">
    <block class="Magento\Cms\Block\Block" name="search-block" after="category.products">
        <arguments>
            <argument name="block_id" xsi:type="string">search-block</argument>
        </arguments>
    </block>
</referenceContainer>

argument name needs to be block_id where static block id is search-block
