We would lean towards the Citroen C3X Shine with the 1.2 turbo engine and six-speed AT. It's a little above your budget but will suit your needs best as it is extremely comfortable, has a superb suspension and the best powertrain for the price. 

For highway driving, it is the best of all the options you have shortlisted because of the brilliant engine and dynamics. However, we have added that Citroen’s dealer network is not the best, and hence, after-sales service could be a worry. 

If you want to play safe, go for the Maruti Suzuki Fronx, it's well equipped, reliable and comes with low-cost maintenance. It’s just that for your budget, you will get the 1.2 petrol mated to an AMT, which is nowhere near as nice to drive as the C3X.
 

The Nissan Magnite and Renault Kiger share their turbo-petrol CVT (automatic), which is a smooth yet powerful powertrain option. 

Both cars have been refreshed recently with quite a few upmarket touches. Between the two, the Magnite looks a bit more SUVish and has slightly better cabin ergonomics. 

If you have a Citroen touchpoint nearby, you must check out the C3 Turbo AT. It is a much better car at a more affordable price tag.

There are a plethora of automatic petrol cars available within your budget. Given your monthly travel is just 200-300km, we will give less weightage to fuel economy and more weightage to driving comfort. As we don't know other preferences, here's a shortlist of the best options by body style -  

Hatchback - Hyundai i20 IVT Asta (O), Citroen C3 X Shine AT
Compact sedan - Honda Amaze CVT ZX
Compact SUV - Nissan Magnite Turbo CVT, Renault Kiger Turbo CVT Emotion

Both the Honda Elevate and the Citroen Aircross have a very good ride quality and are powered by responsive engines. 

For your requirements, you would not go wrong with either. However, to quantify between the two, we would rate the Aircross better in terms of ride quality, engine performance and refinement. Thus, we would recommend you pick the Citroen since driving pleasure and ride quality are very important to you. 

However, make sure there is a dealer in your area and in the areas you plan to drive to, as the Citroen network is very sparse at the moment.   

The Kia Syros is a great option for you due to its spacious cabin and backseats, which recline for more comfort. Furthermore, its boxy design enhances the sense of space inside this cabin. Another good, spacious option is the Citroen Aircross X, which is a large car for compact SUV money. If you have a Citroen showroom near you, it is worth considering.
 

You haven't mentioned your budget, so it'll be difficult to recommend the right car. Since you've mentioned you want something as small as the Maruti Suzuki Baleno, the Hyundai Venue does make a lot of sense. 

You could go for the 1.2L petrol version too, since your usage is going to be minimal. The lower variants are great value for money. If you want a bigger car for similar money, you could look at the Citroen Aircross X. However, your wife will need to get used to its larger dimensions.

The Citroen Aircross X AT is a good SUV with a crucial USP being the extra set of seats in the third row. It isn't a 7-seater but more of a 5+2, which means the third row is good enough for kids and short adults for quick city drives. 

You can also remove the seats entirely and use the space as a big boot. The turbo-petrol engine is responsive and nice to drive, the ride is extremely comfortable, and it has a decent feature list too. If you want maximum practicality, the Aircross X is a good choice. 

The other option worth looking at would be the Kia Syros. The Syros has an unconventional design, but is excellent when it comes to space and packaging. It also has a higher level of quality throughout the cabin. Sure, it does not have an extra set of seats, but it has a spacious rear seat that gets ventilation for the base and a good degree of recline, too. 

Also, Kia's network is more widespread than that of Citroen, and that does help when it comes to after-sales and service.  

Considering your budget, the Citroen C3X Shine 1.2 Turbo Petrol AT is a solid choice. The Tata Punch offers only an AMT, and the automatic variant of the Skoda Kushaq will take you well past ₹11 lakh. 

The C3X’s 1.2-litre turbo-petrol engine is reliable, performs well, and comes paired with a 6-speed torque-converter automatic, which will give you a smooth and enjoyable driving experience.
