First Bike?

So i am turning 18 in 3 months, and I was planning to get an Activa for college commute. My father suggested that I get a Royal Enfield bike, i would have a daily commute of 55km total. Im tall, 6’1” and weigh about 105kg. Ive never driven any vehicles nor scooter nor bikes. I will first learn and then I will start using it. I dont want to ride at high speeds, only city traffic and crowded highways.

My budget is 3lacs. I would love you guy’s suggestions.
