In case anyone can be helped with a resolution, this is how my register-blocks.php is now set up. The style and js is only being loaded on pages when the block is used.
I was creating a slider using Tiny Slider, so this shows how to register & enqueue an outside CSS library and a custom CSS file.

<?php
function custom_load_blocks(){
    // Enqueue the Tiny Slider CSS file from CDN
    wp_enqueue_style( 'tiny-slider-css', 'https://cdnjs.cloudflare.com/ajax/libs/tiny-slider/2.9.4/tiny-slider.css' );

// Register the stylesheet
    wp_register_style( 'tiny-css', get_stylesheet_directory_uri() . '/blocks/tiny-slider/tiny-slider.css' );

    // Register the blocks
    register_block_type( get_stylesheet_directory() . '/blocks/tiny-slider/block.json', array(
        'style' => 'tiny-css', 'tiny-slider-css', // Use the registered stylesheet handle
    ) );

    // Enqueue the Tiny Slider JS file from CDN
    wp_enqueue_script( 'tiny-slider-js', 'https://cdnjs.cloudflare.com/ajax/libs/tiny-slider/2.9.4/min/tiny-slider.js', array(), '2.9.4', true );
    // Enqueue the Tiny Slider JavaScript file
    wp_enqueue_script( 'tiny-js', get_stylesheet_directory_uri() . '/blocks/tiny-slider/tiny-slider.js', array(), '1.0.0', true );
}
add_action( 'init', 'custom_load_blocks' );
