I tried the UEFI boot sequence on a Supermicro server. It boots only
manually, gives some cryptic error while booting automatically. When
entering the path to the EFI loader in a appearing prompt - it boots
fine, but this kills the idea.

I've written a message here about this, so far nobody answered (August,
14th, "FreeBSD doesn't boot automatically from UEFI").

Now it runs on gptzfsboot again, so ....
