Use ACF checkbox value array to find "More like this" - php

Question

I'm using an ACF checkbox to designate categories (called "aims") for Psychology apps/sites. So values would be, say, "Mindfulness", "Well-Being" and "Depression".
Since it's possible to select multiple values, what I'd like to do is have a More Like This where any single post could show other posts that match one or more of the categories of the post.
UPDATE: Here's the code I'm using now, which I'm still not having any luck with:
the_field( 'aims'); /* since I'm on the page for a single post, this gives me the aims for the current post and is currently returning values from the checkbox with multiple selections (as an array, I believe) */
$args = array(
'numberposts' => -1,
'post_type' => 'program',
'post_status' => 'publish',
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'aims',
'value' => 'Well-Being', /* I'd actually like this to use the aims for the current post, but I've hard-coded for testing, and am not seeing any results */
'compare' => 'IN')
));
$more_like_this = new WP_Query ($args);
while ($more_like_this->have_posts()) : $more_like_this->the_post();
$star_rating = get_field('overall_score');
?>
<?php the_title(); ?>
<?php echo $star_rating ?>
<?php endwhile;
wp_reset_query();
?>

If you need a wp query to select some posts where multiple ACF checkbox options must be checked you can do like this:
// Get the array with selected options
$fields = get_field('somefield');
// First create the meta_query variable (AND can also be OR)
$meta_query = array('relation' => 'AND');
foreach( $fields as $field ){
$meta_query[] = array(
'key' => 'name_of_acf_checkbox_here',
'value' => $aim,
'compare' => 'LIKE',
);
}
// args
$args = array(
'numberposts' => -1,
'post_type' => 'postype_here',
'meta_query' => $meta_query,
);
$the_query = new WP_Query( $args );
