I’m kinda blown away.
I STOP a service.
Then I reboot, and it’s STARTED again.
Is there a way, in the GUI to PERMANENTLY DISABLE a service like VSFTP?
I’ll go ahead and vote for ANYONE that is on board with ‘banning FTP everywhere’.
It’s OK. I’ll go flatten the machine again.

AFAIK, no, there is nothing to disable a service from Hestia’s Web UI but command line is your friend 
systemctl disable vsftpd.service
systemctl stop vsftpd.service
v-change-sys-config-value FTP_SYSTEM ''
You can also purge the package:
apt purge vsftpd
