For what it’s worth I found a workaround for anybody needing similar functionality. What I did was use the update_value filter to create custom meta data based on taxonomy term names. Here is a snippet of the code:

function custom_acf_values(  $value, $post_id, $field ) {

	// Set authors
	if( $field['name'] == 'authors' && $value != '' ) :

		$names = '';
		$authors = $value;
	    
	  if( $authors ) :

		  foreach( $authors as $author ) {

		  	$sep = '; ';
		  	if( $author == end( $value ) ) {
		  		$sep = '';
		  	}

		  	$author = get_term( $author, 'authors' );
		  	$name = $author->name . $sep;

		  	$names .= $name;
	  	}
	  endif;
	  update_post_meta( $post_id, 'poster-authors', $names );

	endif;
}
add_filter('acf/update_value', 'custom_acf_values', 10, 3);

However, I am still interested in learning more about the filter I mentioned in OP.
