One possible solution would be to add the 'family' of pages you currently list to your sitemap page, and just have your 'parent' pages listed on the sidebar.
People coming to your site will only visit the 'children' pages through exact-match search terms or through their user journey, so you needn't worry about listing everything on the homepage. Your homepage is there to help entice people to look further - let them discover your other products easily, rather than being given a list of options they must choose from.
That's an opinion - not a solution, really, but it gives you an option at least! Your site would be cleaner and easier to crawl if you just had the parent pages in the sidebar
