I have the option to study geometry this term... I'm not going to though because I'm a big fat baby. It's not directly related to my career interests so unfortunately I'm going to have to jettison it for now and basically limit my understanding of GM to fluffy stuff. I doubt I would enjoy it anyway, tensors and the like just aggravate and bore me. It's so messy in fact that nobody really got anything useful out of Einstein's theory for decades. 

I would say that GR would expand your mind, but that's only if you get past the enormous barriers to beginners. Unfortunately, after only a single semester of learning about it, you would most likely be totally bogged down in the details of working with tensor notation. 

In classical physics (of which the relativities are the current(!) completion), "photon" is essentially equivalent to "null world line", i.e. they are the paths through spacetime (if such a path exists) that connect two points with zero "length" between them.

It's a very pure course, I don't believe any application exists other than general relativity. There's only a finite number of courses I can realistically do, and things like electromagnetism, waves and definitely statistics are far more important for what I want to do. I am doing some algebra too though (groups, rings, modules) because it seemed like the most likely course to be useful, and I was not too bad at it last time.

Differential geometry is even being used in fincance but I totally appreciate your other points, especially regarding an upper bound on courses. Very good intuition on algebra being useful though.
