Welcome!
Everyone seems to have their own break-in procedure. The manual vaguely states not to do full-throttle starts or drive at a constant speed for the first 800km, and to avoid hard stops for the first 300km. Follow that and you should be ok.
If you plan on owning it long-term, I'd suggest ignoring the oil-life monitor and get the first few oil changes every 5,000km.
As for quirks; do you mean common problems? Swaybar endlinks failing prematurely seem to affect all models. The only real complaint I have with the car is that the auto-headlights are waaaayy too sensitive.
