Fantastico offers and supports only certain scripts because of compatibility reasons.
hostlantern has replaced Fantastico with Softaculous, which offers a lot more scripts for easy installation.
If you need a script installation that you cannot find in Softaculous, you can request a manual script installation from SiteGround by logging in to your hostlantern Customer Area and going to Support -> Open a Support Ticket -> Script Installation.
cPanel is easy to work with when you have the right host to support you. If you need a reliable partner to help you manage your website with cPanel, check out our cPanel hosting services!
