Need 2 blog pages in theme with custom loop on second page

I have a website that needs 2 blog pages. I found this code that does the trick:

<?php 
// the query
$wpb_all_query = new WP_Query(array('post_type'=>'post', 'post_status'=>'publish', 'posts_per_page'=>-1)); ?>

<?php if ( $wpb_all_query->have_posts() ) : ?>

<ul>

	<!-- the loop -->
	<?php while ( $wpb_all_query->have_posts() ) : $wpb_all_query->the_post(); ?>
		<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
	<?php endwhile; ?>
	<!-- end of the loop -->

</ul>

	<?php wp_reset_postdata(); ?>

<?php else : ?>
	<p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>

But I need it to be identical to the way the code works on my index.php. Here is the code for that:

<?php while (have_posts()): the_post() ?>
                    <?php if ($wp_query->current_post % 2 == 0): ?>
                        
                        <?php if(!has_post_thumbnail() || get_theme_mod( 'md_post_thumb_all')) : 
                        $no_featured_img_list = "no_featured_img_list";
                        endif; ?>

                        <article>   
                            <div class="section group">
                                <div class="col span_1_of_2">
                                    <?php if(has_post_thumbnail() && !get_theme_mod( 'md_post_thumb_all')) : ?>    
                                        <div class="post-img">  
                                            <a href="<?php echo get_permalink() ?>"><?php the_post_thumbnail('mini-thumb'); ?></a>  
                                        </div>
                                    <?php endif; ?> 
                                </div>
                                <div class="col span_1_of_2">
                                    <div class="blogcontent">
                                        <h2><a href="<?php echo get_permalink(); ?>"><?php the_title(); ?></a></h2>   
                                        <?php the_excerpt(); ?>
                                        <br>
                                        <a href="<?php echo get_permalink(); ?>" class="readmore">READ MORE</a>
                                    </div>

                            </div>

                    <?php else: ?>
                        <?php if(!has_post_thumbnail() || get_theme_mod( 'md_post_thumb_all')) : 
                        $no_featured_img_list = "no_featured_img_list";
                        endif; ?>

                        <article>   
                            <div class="section group">

                                        <?php the_excerpt(); ?>
                                        <br>

                                        </div>
                                    <?php endif; ?> 
                                </div>
                            </div>
                        </article> 
                    <?php endif ?>
                <?php endwhile ?>

Can someone help me? I’m having trouble wrapping my head around what that would look like. Thank you in advance!
