CAFS seems much more interesting in my honest opinion. If you're interested in families, parenting styles etc it might be the one for you.
But it seems like you really like the writing and memorising subjs (eng, legal, ancient, bio), so maybe modern history would be good as well since it suits.
Overall it really depends on how much you find the subjects interesting. CAFS might be more interesting and relaxing since (at my school at least), the history exams and assignments are clumped together and that might cause unnecessary stress.
> you have 10 units that you chose that you're certain about. They'll probably go to your ATAR because you like the subjects enough. Just pick whichever sounds more interesting and roll with it
