Hi @jrstaatsiii,

Thank you for sharing the solution. I will now copy the same to this forum so that it can help out a fellow dev in future:

<?php
/*
 * Returns the first instance of a given layout option
 * @param - $id - the id of the post you are trying to target: '' by default
 * @param - $fc_field - the name of the ACF flexible field: 'content_blocks' as the default
 * @param - $fc_layout - the name of the flexible content layout: 'visual_editor' as the default
 * @return - mixed
 * @todo - test different types of returned content. at the moment, I am only using this for returning a string
*/
function get_first_instance_of_content_block( $id = '', $fc_field = 'content_blocks', $fc_layout = 'visual_editor' ) {
	
	if ( class_exists('acf') ) { 
	
		if ( have_rows( $fc_field, $id ) ) { 
		
			$content_blocks = get_field( $fc_field, $id );
			$content = array();
		
			foreach ( $content_blocks as $block ) {
				if ( $block['acf_fc_layout'] == $fc_layout ) {
					$content[] = $block[$fc_layout];
				}
			}
		
			reset($content);
		
			return $content[0];
	
		}
	
	} else {
		
		return '<p class="error">Advanced Custom Fields is required for <code>get_first_instance_of_content_block()</code> to work.</p>';
		
	}
	
}
