IMO you should concentrate the money on the display and the speakers/sub, and not on the receiver. All receivers basically sound same, i.e. speakers will make a FAR bigger difference than anything else. Split the budget into audio and video categories and within audio spend most of it on the speakers.
Even entry level receivers these days come with features like Airplay, 4K support, and network playback. When you spend more you get features such as preouts (for connecting external amps, which if you don't care about its unlikely you need), a graphical OSD, more power, and better room correction software (e.g. YPAO, Audyssey etc). Onkyos in general are not known for being reliable as you can see in the various support threads here. You should also look at closeout prices on last years models (this year doesn't have much new).
I wouldn't spend $250 on a BR player, even a basic $100 unit of which there are many, and often go on sale, will give the same picture and video quality (its all over HDMI), have Netflix etc. You mentioned a games console, since those are coming out in a few months and if you plan to buy one, you might want to wait, they will have the BR drive.
For speakers I'd also recommend an Internet direct retailer, those are quite a bit cheaper.
