Lily's biggest issue is that she doesn't have any control panel or other UI. All you get is FTP and phpmyadmin for databases. It doesn't talk to a Plesk account, and does not run Plesk itself. While we do require a Plesk account before you can get a Lily account, there is no actual technical reason for this anymore unless you need email service (back when we ran cPanel, this was actually needed for DNS and other essential functionality).
It supports .NET 4.8, 5.0 and 6.0, as well as pretty much all versions of PHP.
Will that work for you?
