After doing some digging in your ACF code, I may have a more targeted solution from the acf_get_value() function. This is untested, but assuming this is where the value is cached, it should easily be cleared on post update hook.

	public function acf_clear_object_cache( $post_id ) {
		if ( empty( $_POST['acf'] ) ) {
			return;
		}
		
		// clear post related cache
		clean_post_cache( $post_id );
		
		// clear ACF cache
		if ( is_array( $_POST['acf'] ) ) {
			foreach ( $_POST['acf'] as $field_name => $value ) {
				$cache_slug = "load_value/post_id={$post_id}/name={$field_name}";
				wp_cache_delete( $cache_slug, 'acf' );
			}
		}
	}
