I use a similar setup, but use a USB for my boot drive that has the lvs partition encryption keyfile. I find it much handier since my computer is not near my server. I can boot and then walk upstairs and it is ready, and remove the USB later.

Then there is no way to brute force the decryption or get a password out of me. Also, when the USB is removed and put in a safe place, there is no way to modify the boot partition or UEFI either.

Then I have a password encryption on my data harddrives that I don't know the password to, but is on my password manager.

The thing about being paranoid about this stuff is that I probably focused on the wrong thing. A smash & grab is completely protected against, but that is like a 0.1% chance anyway and a 0.1% chance on top of that 0.1% chance that it would be targeted enough that they would even try to decrypt it.

Full disk encryption is really only usefully at all for an unpowered system. Network hardening will probably take care of 99.99% of attack attempts where encryption is 0.01%.

Even for a laptop, if it gets stolen in public, it is still running and can have the keys extracted or break into the running system if someone really wants to hack it. They wouldn't even try to reboot and break the disk encryption probably...

Too much info, but I guess I am just rambling about how dumb my approach probably is 😅

Thanks, I'd like to know more about your public-facing setup using cloudflare

You might be interested in setting up network bound encryption via Clevis and Tang. I use a hidden pi zero in my house acting as a Tang server. It's great being able to reboot any of my encrypted servers without having to manually unlock disks.
