Buy something you like the look of, try and keep it as light as possible (light bikes are so much more exhilarating) and keep it under 100hp. Seriously, a light 80hp bike is fast as fuck unless you're jumping out of a Mclaren or something. I've got two sporty bikes, one makes 160hp the other 80 on a good day. I have more fun on the latter.
Blackbird: 260kg, 160hp, 30mpg, 24L? Tank
F3: 200kg, 90hp, 40mpg, 17L tankEasier to move when parking, easier to straddle in traffic, squeezes through smaller gaps, tighter steering locks, feels rapid with the limited fairing, gotta stop for fuel at the same distance but it’s costing me way less. Also, does not hit warp speed in all gears instantly.
I think you'd be fine on something like a Street Triple - it will blow your mind how quick it is, but they're light and friendly and you don't have to wick it up until you want to. They're also somewhere between a twin and a four cylinder in power delivery for what that's worth.
Around traffic there's a good crossover as far as defensive riding goes between bikes and mo'bikes, so that should stand you in good stead. The big difference is bike handling - street bikes have bugger all in common with bicycles. Take your time and be cautious, practice some hard stops and quick changes of direction and learn to look a LOT further up the road. Upside, you'll have a cracking bike once you start getting into the groove.
You could do all this on an MT10 or something but it would be easy to end up afraid of the bike and at that point it's tough to learn anything. (and no fun!)

Do some test rides! Other suggestions - Aprilia RS660 or Tuono, Yamaha R7, KTM790,
