   Here is an example of handing a custom post type which holds an event date field in metadata and where I wanted the Query Loop to display posts sorted by the event date rather than the post date. I also wanted to exclude dates in the past.

   add_filter( 'query_loop_block_query_vars', 'wpdocs_filter_query' );
   function wpdocs_filter_query( $query ) {
       // ignore if the query block is not using this post type
       if ( 'wpdocs_event' !== $query['post_type'] ) {
           return $query;
       }
   
       // always exclude events with dates in the past
       $query['meta_key'] = 'eventDate';
       $query['meta_value'] = date( 'Y-m-d' );
       $query['meta_compare'] = '>=';
   
       // If date order was chosen in the block settings, change to use the Event date instead of Post date
       if ( 'date' === $query['orderby'] ) {
           $query['orderby'] = 'meta_value';
       }
   
       return $query;
   }

   Example of modifying the query based on the class name set on the Post Template block:

   function wpdocs_randomize_query( $query, $block ) {
   
   	$block = $block->parsed_block;
   
   	if (
   		isset( $block['attrs']['className'] )
   		&& false !== strpos( $block['attrs']['className'], 'randomize-content' )
   	) {
   		$query['orderby'] = 'rand';
   	}
   
   	return $query;
   }
   
   add_filter( 'query_loop_block_query_vars', 'wpdocs_randomize_query', 10, 2 );
