I recommend 1 over 2. In fact, I would recommend replacing 2 altogether with

2. Rsync disk volumes and text dump of catalog over SSH to the remote
location

The advantage of having an SD at the remote site is that it makes
possible writing Copy jobs of the incremental jobs to the remote site
and writing Virtual Full jobs to the remote SD. The remote SD is
"initialized" by hand delivery of Full jobs media. This drastically
reduces bandwidth requirements, since only incremental jobs need ever be
transmitted.

Since the communications can be TLS encrypted, I consider the Bacula
communications to be as secure as any other TLS encrypted service. The
"safest way possible" is a subject of much debate. I have a client who
hand carries encrypted tapes to a bank safe deposit box.
