f/2 vs. f/1.8 clearly isn't an advantage for the 35mm. The most you can say is that the advantage of f/1.8 over f/2 is small enough that it rarely matters much. There's no room for question that the 50mm wins in this respect though. The only question is whether it's a big enough win to care much about.
43 vs. 31 degree FoV is (IMO) pretty close to neutral. A wider angle may favor your shooting style, but that's certainly not universal. If there was a preference here, I'd say it leans in favor of a longer lens, especially for beginners -- beginners are often shy about approaching subjects as closely as would be ideal; a longer lens can help compensate for that to at least some degree. Of beginners pictures I've looked at, I'd say too loose of composition was a problem at least five times as often as too tight of cropping.
Making the total kit compact again seems to be mostly treating your own shooting style as how the world works. If I had to use APS-C with only two primes, I can see 50mm as one of the choices a lot more easily than 35mm. 50mm is long enough to use as the "long" lens for quite a few purposes (i.e., most things other that sports and wildlife). You can pair it with, say, a 24mm and cover quite a bit reasonably well. With 35mm, you nearly need both shorter and longer focal lengths, so your minimum becomes a three-lens set, so the 50mm wins again.
In the end, I think it mostly comes down to shooting style -- both what sort of subject matter you like to shoot, and how you like to shoot it.
I should probably add that on APS-C, most primes never really feel "right", at least to me. Maybe it's just because I shot film for so long, but none of them ever seems to really give the right "feel" for most pictures. For example, portraits with a 50mm either end up a bit loose or else overemphasize people's noses too much. With the 85mm, you end up having to back away so far that even though the subject fills the frame, there's much less feeling of immediacy and connection -- to me it's more like a really good wildlife photo than a portrait.
