I don't know what third-party disk encryption services there are available for
FreeBSD nor do I know what the status of gbde is currently, but there is no
inherent reason that a third-party encryption service would be any more stable
or robust than one that's built into the OS. In fact, I'd argue just the
opposite, as the people who wrote gbde also work on related parts of the
FreeBSD kernel and nearly all of the core FreeBSD developers are well-known
for their ability to design and write quality, stable code. They would also be
the first ones to notice a change to the kernel that would adversely effect
gbde and probably also the first ones to fix such a problem.

No, otherwise there would be no point in encrypting the data on the disk.
Encryption means that even if someone were to get their hands on the physical
disk (which is always considered the worst-case scenario, from a security
standpoint) and read all of the data off it, they could never use it to gain
any information since the data would appear scambled unless they decrypted it
with the appropriate key (the password, in this case).

In other words, it's not the operating system that allows/disallows access to
an ecrypted disk, it's the mathematical encryption algorithms. Similarly, disk
encryption has nothing to do with allowing/disallowing access to the system,
only its data.
