Since most of your usage is inside the city, bikes like the Hero Xpulse 210, Royal Enfield Bullet / Classic / Hunter 350, Honda CB350 trio and the TVS Ronin will make for good options to consider depending on your preference.
If you do want something a touch sportier but not very rambunctious, then the KTM 250 Duke also makes for a great companion.
A test ride of everything you decide to shortlist will help you make a decision.
