I thought boot code was damaged or missing, so I tried:

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada2

Rebooted, but still getting "inconsistent nvlist contents" error.

How can I fix this?

First, with these commands you have destroyed your efi loaders. You should have selected -i 2 for both commands.

But you boot the first stages anyway, so I guess you are in BIOS booting mode. Redo these commands with -i 2. I ain't sure this will change something, that said.

Optionnally, you can restore your efi loaders with the reformatting of efi partitions. See here for instructions: https://forums.freebsd.org/threads/update-of-the-bootcodes-for-a-gpt-scheme-x64-architecture.80163/

Thank you for the quick reply Emrion. Followed your suggestions and to my great relief, it booted!

Good. Now go fix those efi partitions, because you destroyed those. If you happen to switch to UEFI booting the system will fail to boot entirely.

Always pay attention when updating the bootcode, gptboot(8) or gptzfsboot(8) need to be written to the freebsd-boot partition, this may or may not be the first partition.
