Aside from which bike, I would also highly recommend finding as much online training as you can for road strategy, if not in-person training. DanDanTheFireman, Motojitsu, and MCRider are all fantastic places to start, and are loaded with drills and exercises focused on beginner and novice riders. DDFM has hundreds of videos from the compilation channels where he shows clips of riders doing something wrong or doing something right, and will break them all down to figure out exactly what happened and why. E.g., you see an "open lane pattern" about 600 times in videos, and you'll instinctively be ready for that car to jump into your lane in real life.
