If it’s a server for self hosting you definitely don’t want anything that requires interaction at boot.
There’s a project that allows unlocking LUKS with a decryption key retrieved from another machine in your network. I don’t recall the name but someone hopefully will.
The idea is that put the key on, say, a raspberry pi zero w that you hide somewhere in your house so that if someone steals your server they don’t have the key.
