I'm thinking something like +45.

Another concern is optimal tire size- I'm not a fan of skinnier, low profile tires (though I know the profile increases in size as a tire widens) and was thinking of 265/40/18. Also in consideration is 275/35/18. Not a fan of the super stretched look.
I would highly advise staying within 2% of stock diameter. The 275/35R18 is closer to stock size, and will probably be an easier fit because despite being wider than stock STI tire, it's 0.5% shorter, instead of being 2.6% taller. 265/35R18 is still less than 2% smaller than the stock STI size, and it's actually EXACTLY the same as the stock 235/45R17 WRX size tire.

Paired with the wheels will be a set of H&R coilovers. Just looking for something decent for the street; won't see any track/race use. Is there anything else better for the money?
We've departed from wheel and tire fitment here. Let's stick to that topic in this thread.

Just to be clear, you need the spacers with that particular wheel in that particular fitment. Many other wheels with the same size and offset will not require spacers.

Why are you so focused on the 10" wheel width? For a 265 I'd go with a 9.5" wheel.
