You can use the CiviEvent widget to add two types of widgets for upcoming public events from CiviCRM. There’s no limit to the number of widgets you can add of either type. You can include the widgets in the sidebar like normal, or you can include them via shortcodes in the body of your posts.
<h4>CiviEvent List Widget</h4>
This widget is a basic, flexible listing of upcoming events that are marked as public. You have options to customize the appearance and number of events. There is the option to add the event’s city, state, and/or country to the listing if “Show location” is enabled on the event.
<h4>Single CiviEvent Widget</h4>
This widget displays a single public event from CiviCRM. By default, it will display the first event from the current day or the future, or you can set an offset to skip one or more and display the second or third upcoming event. You may display the location if “Show location” is enabled on the event.
<h4>Shortcodes</h4>
Both widgets are available to be inserted into the body of a post using a shortcode. Use the <code>[civievent_widget]</code> shortcode for the events listing and the <code>[civievent_single_widget]</code> shortcode for the single next (or offset) event. The available parameters for the shortcodes are as follows:
<ul>
<li><code>title="Your Title"</code> The widget title (default: “Upcoming Events” for the list widget, or the event’s title for the single widget).</li>
<li><code>summary=1</code> Display the event summary. Omit the parameter or set it to 0 to hide the summary. (List widget only.)</li>
<li><code>limit=5</code> Display the specified number of events (default: 5). (List widget only.)</li>
<li><code>alllink=1</code> Display “view all” with a link to the page with a full list of public events. Omit the parameter or set it to 0 to hide the link. (List widget only.)</li>
<li><code>wtheme="mytheme"</code> The widget theme (a class added to the widget div). Set a new one and handle it in your theme’s CSS. (Default for list widget: “stripe”, with “divider” as an alternative. Default for single widget: “standard”.)</li>
<li><code>divider=" | "</code> The location field delimiter (default: comma followed by a space).</li>
<li><code>city=1</code> Display the event’s city. Omit the parameter or set it to 0 to hide the city.</li>
<li><code>state="abbreviate"</code> Display the event’s state/province. Default is “none”, which will display nothing about the state or province. Display options are “abbreviate” for the state/province abbreviation or “full” for the full name.</li>
<li><code>country=1</code> Display the event’s country. Omit the parameter or set it to 0 to hide the country.</li>
<li><code>offset=2</code> Skip the given number of events before displaying the next one (default: 0). (Single widget only.)</li>
<li><code>admin_type="simple"</code> Whether to use the “simple” (default) or “custom” display options (as appear in the widget settings). The <code>custom_display</code> and <code>custom_filter</code> parameters only function alongside <code>admin_type="custom"</code>. The <code>summary</code>, <code>alllink</code>, <code>divider</code>, <code>city</code>, <code>state</code>, and <code>country</code> parameters only function when <code>admin_type="simple"</code> (or reverting to the default). (List widget only.)</li>
<li><code>custom_display='{"event_title_infolink":{"title":0,"prefix":null,"suffix":null,"wrapper":1},"description":{"title":1,"prefix":null,"suffix":null,"wrapper":1}}'</code> Custom options for displaying results when <code>admin_type="custom"</code>. The value should be an object written in JSON. Each property name should be a field to display, and the property value should be an object with the following properties: <code>title</code> (1 or 0: whether to display the field name), <code>prefix</code> (<code>null</code> or a string with markup to precede the field), <code>suffix</code> (<code>null</code> or a string with markup to follow the field), and <code>wrapper</code> (1 or 0: whether to wrap the field with the default wrapper elements. You may configure a widget using the standard widget interface, click “Show JSON”, and copy the JSON into this parameter. If <code>custom_display</code> is missing, the listing will revert to displaying in the “simple” mode despite the <code>admin_type</code> value. (List widget only.)</li>
<li><code>custom_filter='{"start_date": {">=": "2015-12-16"}, "is_public": 1, "options": {"sort": "start_date ASC"}}'</code> Custom options for filtering results when <code>admin_type="custom"</code>. The value should be an object written in JSON. The object should be a valid set of parameters for the CiviCRM API. The default is to list all public events starting on today’s date or later, sorted by start date ascending. (List widget only.)</li>
<li><code>event_type_id=3</code> Display Event with event type id 3 (default: show all event). (only work with admin_type=”simple”.)</li>
</ul>

Caldera Forms CiviCRM

I have been using this plugin via GitHub for quite some time and am happy to see it on wordpress.org

Having the ability to integrate our CRM data with Forms by Caldera is indispensable.  The plugin is well coded and the developer has been responsive to fixing issues and adding features.

I cannot say enough good things about this.
