Snippet inside query loop - number field (with logic)

Hey y'all. I seem to be getting stupid with query loop blocks. You came through last time with the image array, now I need to do something similar with a number ACF field, and I'm sure I'm just messing up the syntax.

In a nutshell, I have 3 product price fields:
pdf_price
pod_price
product_price

For the archive and single pages, an if statement checking if the field has value and then displaying it WORKS (then using a shortcode with the portable hook shortcode method). This doesn't work for the query loop, as I learned on the last go-round with the images. Here is the code you gave me to display images (set to array with logic) in a query loop:

add_filter( 'render_block', function( $block_content, $block ) {
    
    $image = get_field('product_main_image');

    if ( !is_admin() 
        && $image
        && ! empty( $block['attrs']['className'] ) 
        && strpos( $block['attrs']['className'], 'my-query-header' ) !== false
    ) {
        $block_content = '<img class="product-main-image" src="' . esc_url($image['url']) . '" class="product-main-image" alt="' . esc_attr($image['alt']) . '"/>';
    }

    return $block_content;

}, 10, 2 );

Giving any block in the query loop the class of "my-query-header" displays the image beautifully. Now - how do I do the same thing with 3 different number fields? (if no data exists in a particular field, it shouldn't display)

Thanks, as always for your time.
