With your Rs 10 lakh budget, a strong choice is the Honda Amaze VX MT.
It fits well within budget, offers good comfort, and carries a 5-star Bharat NCAP adult safety rating. The petrol engine is tried and tested, and it has a comfortable ride quality. With the manual, you can expect real-world mileage of around 14 to 15 kpl.
If you want an automatic, consider the Amaze CVT in the lower V variant, which fits within your budget. The CVT gives you a premium automatic experience, unlike cars in this price bracket that offer basic AMTs, and for a long daily commute. It will make a noticeable difference in smoothness and ease of driving.
