Assam trip Info

Hi, I’m visiting Assam with my family (2 adults & 2 kids) for a vacation this month for some peace, nature and wildlife and would appreciate any tips and info. Below is our itinerary. We plan to spend 2 days at a homestay at the Jia Bhareli river and from there head to Kaziranga for 3 nights and from there to Cherrapunji for an another three nights. We are planning to hire a tourist car for the duration but the thought of hiring a self drive car has also crossed my mind (for a part of the trip if not whole). Is the self drive scene in Assam reliable and safe? Or should we just stick to hired cabs? Also any recommendations for authentic, non touristy food in Guwahati and the others places will be highly appreciated. We love pork/beef/fish and want to eat where the locals and rickshaw/cab drivers eat. Thanks in advance.
