I am a professional mechanic and looked at your bike. A qr is a quick release. Front hubs come in both qr and thru axle variants–mid to high end current production forks are nearly all thru axle

All Shimano hydraulic brakes in current production are decent, and I'd take any of them over an Elixir. They are prone to failure of the master cylinder in the brake lever and generally kinda suck.

You'll get parallel spokes around the valve if you treat a symmetrically drilled rim as either Type A or B. I'd never suggest lacing with angled spokes around the valve.
