Hey @anybodesign
You should able to do that via get_posts() too.
The most problem you don’t use the proper order value for that.
I think you want to change the ‘order’ like this:
$posts = get_posts([
'post_type' => 'product',
...
'meta_key' => 'your_date_field',
'orderby' => 'meta_value_num',
]);
The key is the meta_value_num when you order by number / date type of fields
