I'm not really sure on the design goals, so these are just my personal
The file db scatters keys over multiple files, making it harder for
attackers to find key material.  It will also be faster.  However the
SQLite3 is easier for operational environments to backup (just one file)
and is more transactional in that respect.  Many just use file based as
it is the default.
