Your approach is almost correct, but there are a few issues to address:

The acf/update_value action does not directly pass the Google Maps field data as an associative array. You need to ensure that $value contains the data you’re expecting.

Here’s the corrected code:

function update_state_short( $value, $post_id, $field ) {
    // Check if the value contains the 'state_short' key
    if ( isset( $value['state_short'] ) ) {
        // Update the 'state_short' ACF field with the new value
        update_post_meta( $post_id, 'state_short', $value['state_short'] );
    }

    // Return the original value to ensure the ACF field is saved correctly
    return $value;
}

// Hook into the ACF update_value action for the specific field key
add_filter( 'acf/update_value/key=field_5e5a38be195bc', 'update_state_short', 10, 3 );
