Hi Michael,
First of all, let me applaud the approach you are taking - putting out there what works best for you and seeing who thinks they have a compatible/aligned situation. Smart move!
There are probably a few ARTCCs that would be a good fit for you -- 2-3 perhaps -- and my guess is that that they are currently all very similar in their ability to offer you what works best for you.
That said, I'm of course just a bit biased and so I offer Boston for your consideration (though if you ask me my opinion of any others I'll be happy to give you a fair and impartial opinion).
Realism: We hit the nail on the head, I believe, aligning to your Realism desires.
Traffic: Boston is certainly a major airport that draws a fair amount of traffic, yet a couple of our Class C airports draw their fair share, at times, also (BDL, PVD, PWM, BGR to name the busier class Cs). As an example, I was controlling all of Boston Center about 5 hours ago and had more traffic into and out of BDL than BOS....)
Positions: We don't have enough controllers to warrant a scheduling system of our own, though we don't discourage you posting your desired times anyplace, e.g., vRoute. Should we get to that point, however, I'm happy to institute a scheduling system. We just haven't ever had that need in the 5 years I've been here. I welcome that problem, however!
Schedule: We're on the East Coast too! The evening hours you mention are our busiest times, with the later night (10pm-1am) coming next. 6-9am is pretty dead, as a rule, unless the position is staffed..... When we're on, we attract folks, but mainly Europeans, etc. that are looking to get some US exposure.
Training: Though we are bound to follow GRP which mandates initial training just to meet the basic requirements, we do liberally use off-peak authorizations at our major airport, Boston. And you get there quite quickly once you've demonstrated basic competence at one of the minor fields. We also liberally employ training in the Sweatbox simulator, which allows you and the instructor/mentor the ability to select the traffic load that is right for you. You can intern during off peak on your own to build your confidence while getting targeted training in the ER, with the instructor ensuring you get the right exposure to the right training scenarios and right pace to push your envelope... and lead to certification the fastest.
Have a look at our website

Kind regards,
