Editing variable pricing to add styling

Hi,
I am trying to edit a specific category of products to make the archive page clearer to our customers. I want the pricing loop to only be amended for a specific category and only when certain variations are present. The category is ‘steaks’ and the variations are ‘per-steak’ and ‘per-kg’.

For every other category/product type combination, I want the standard WC code to apply and I don’t want to have to write exceptions in my function for every different situation. My code currently looks like this:

function iconic_variable_price_format( $price, $product ) {
    $prefix = '£';
	
    $min_price_regular = $product->get_variation_regular_price( 'min', true );
    $min_price_sale    = $product->get_variation_sale_price( 'min', true );
    $max_price = $product->get_variation_price( 'max', true );
    $min_price = $product->get_variation_price( 'min', true );
	$upload_dir = wp_get_upload_dir();
    $price = ( $min_price_sale == $min_price_regular ) ?
        wc_price( $min_price_regular ) :
        '<del>' . wc_price( $min_price_regular ) . '</del>' . '<ins>' . wc_price( $min_price_sale ) . '</ins>';
	    
	if ( is_product_category('steaks') && $product->is_type( 'variable' ) ) {
		foreach ( $product->get_available_variations() as $key => $variation_data ) {
			$weight = $variation_data['weight']; // Get weight from variation

			return ( $min_price == $max_price ) ?
					$price :
					sprintf('<div class="per-piece"><img src="%s/2022/06/steak-var-icon.svg"> %s%s <span class="weight">/ %s</span></div><div class="per-kg"><img src="%s/2022/06/kg-var-icon.svg"> %s%s <span class="weight">per kg</span></div>', $upload_dir['baseurl'], $prefix, $min_price, $variation_data['weight_html'], $upload_dir['baseurl'], $prefix, $max_price);
    	} 
	} elseif ( !is_product_category('steaks') && $product->is_type( 'variable' ) ) {
		foreach ( $product->get_available_variations() as $key => $variation_data ) {
			$price = ( $min_price_sale == $min_price_regular ) ? 
                wc_price( $min_price_regular ) : 
                    '' . wc_price( $min_price_regular ) . '' . '' . wc_price( $min_price_sale ) . ''; 
                    return ( $min_price == $max_price ) ? 
                        $price : 
                            sprintf('%s', $price);
    	} 
	}
}
add_filter( 'woocommerce_variable_sale_price_html', 'iconic_variable_price_format', 10, 2 );
add_filter( 'woocommerce_variable_price_html', 'iconic_variable_price_format', 10, 2 );
add_filter( 'woocommerce_show_variation_price', '__return_true' );

function bd_rrp_price_html( $price, $product ) {
	if ( is_product_category(16) && $product->is_type( 'simple' ) ) {
		$upload_dir = wp_get_upload_dir();
		$return_string = '<div class="per-kg"><img src="' . $upload_dir['baseurl'] . '/2022/06/kg-var-icon.svg"> '. $price .' <span class="weight">per kg</span></div>';
		return $return_string;
	} else {
		$return_string = $price;
		return $return_string;
	}
}
add_filter( 'woocommerce_get_price_html', 'bd_rrp_price_html', 100, 2 );

This is working well for the specific situations, but it is breaking other situations, for instance when a sale is placed on a variation within the category or for variation products outside of the category.

Please could I have some help with this? Thank you!
