Hi Bipul ji,
Greetings !!
My total running is around 600 km per month (25 km per day both ways), in the city traffic mostly alone. It took me nearly 2 hrs in traffic with all sort of clutch-break-clutch-gear-brake and so on. XUV 500 gives me a mileage of 10 km per litre and a lot of back pains 
Indeed an Automatic choice is real boon and considering
> Traffic
> Age
you will find it to be the best for need. A 2 Pedal Technology car where
a) Left foot is relaxed while drive
b) Car has creep mode which makes utmost ease in bumper to bumper traffic - where one can control drive through Brake only as automatically pick speed of 7 kmph without even pressing accelerator
is what the need of hour
I also get in to your point where maximum usage is in city condition and having a car with comfort oriented suspension and electric steering as against hydraulic one can make things easy.
Basis Different choices
See - one has to make a trade off with low mileage
If you seeking a large size SUV and non-hybrid one - like XUV700 Petrol or MG Hector - Single Digit mileage is something which need to be accepted. Also - 9 kmpl is something which can be optimistic too at times, as in bumper to bumper traffic and in extreme conditions - car mileage can drop to 7 to 8 kmpl too at times
MG Hector Savvy Pro CVT has everything in terms of
> Comfort where suspension is tuned on soft side. For city use where relative light steering, comfort oriented suspension and ADAS Features including traffic jam assist where car can steer too in traffic jam of city (having white marking on road) to be in lane and use autonomous brake to offer supreme convenience to drive
> For City Use - basis steering, suspension, features and space for 4 members - an excellent pick
> Pretty Spacious for 4 members and lifestyle experience felt
What you wont like:
a) Mileage which is actually lowest in segment and will
b) Other SUV Cars like Harrier, Safari, XUV700, Scorpio N has more superior handling response and feels more macho on high speed
XUV700, XUV400: Its a myth to think that due to EV - resale will be impacted
EV are still in nascent stage and considering challenges in terms of
> Upfront Pricing
> Range Anxiety
> Charging Infra
> Battery Life Replacement Concerns
> Changing EV Tech
infact it will still take a long time for EV Cars Tech to be developed and grew in Indian Market
Dont foresee any threat to Internal combustion engine resale in even next 10 yrs basis fact that over 20 Million New Internal combustion engine cars projected to be sold in next 5 yrs - with many more millions sold earlier too
Rest - i second your opinion on Mileage, waiting on XUV700 and XUV400 part
Hyryder: Basis fact that your monthly usage would be just 600 Kms (other than long term) - spending too much on strong hybrid wont serve purpose.
Best Car: To View MG Hector Savvy Pro CVT has everything which makes it ideal for your specific need except Mileage part
To make numbers in context - if you say getting in like 8 kmpl in realistic scenario - it will mean Rs 1500 a month as extra outflow in terms of Petrol (as against a car which would have delivered in 10 kmpl), translated to Rs 18000 a year - to Rs 1.5 Lakh in around 7 yrs by which can consider EV tech to be developed too in 2030 and can consider a replacement then
So it shouldnt be an issue and if rest all consideration meeting in
> Comfort
> Lifestyle
> Relaxed drive
> Space
can turn out as ideal one.
Have test drive and consider same
