If you are prepared to take your test then you can take you choice of what you want and will not be limited by the 2 year rule or CC.
I've ridden a Varadero 1000 (guy I work with has one) and it is lardy to ride and very top heavy. If the 125 version is top heavy, then i'd steer clear of it and go for something with a more conventional riding position.
Over 20 miles, I'd rather go for something bigger than a CG125 as you will struggle to match the speed of the traffic and will spend much of your time being overtaken, maybe a 400 or 500 commuter like the ER-5 as mentioned, or even an SV650 which is a lovely newbie bike with good handling, respectable brakes, good economy, comfortable as well, but not enough performance to scare you.
