XavinNydek

This plugin adds the ability to put a tag in your page entry and have it display a list of pages. By deafult it will 
show the subpages of the page that it is on, but it will accept any of the options the 
<a href="https://codex.wordpress.org/Template_Tags/wp_list_pages" rel="nofollow ugc"><code>wp_list_pages</code></a> template tag 
will except <code>title_li</code> and <code>echo</code>. It is very simple to use, just put <code>[xls]</code> in the entry for your page where you want the list to appear.
There is one option in addition to the <code>wp_list_pages</code> ones. Specifying a <code>css_class</code> will override the default of 
 xls_list for the class of the surrounding <code>ul</code>.
It supports multiple uses of the tag with different options on one page.
Here are a few examples of valid tags:
<pre><code>[xls depth=2]
</code></pre>
Shows two levels of the subpages of the current page.
<pre><code>[xls child_of=10 exclude="13, 15, 33"]
</code></pre>
Shows all children of the page with id 10, excluding pages 13, 15, and 33.
<pre><code>[xls child_of="0" show_date="modified"]
</code></pre>
Shows all pages, and shows the last modified date of each page.
Check the <a href="https://codex.wordpress.org/Template_Tags/wp_list_pages" rel="nofollow ugc"><code>wp_list_pages</code></a> documentation for all of the possible options.

Xavin's List Subpages

I know it hasn't been updated for some time but I have been using it for many years and currently running it on WordPress 4.3.1 without any issues.
Such a simple yet useful concept and this plugin does it well. Listing the sub pages of a page inside itself in a bullet list with a shortcode.



Still the best list subpages plugin

Adds a tag that you can use in your pages to display a list of it's subpages.
