If you are married then go for the JBL 1300 soundbar.
I designed my sister's house and designed the living room to incorporate a good home theater system but she didn't allow us even when there was enough space. Now the wires for surrounds are just lying there underground with no use.
So probably your wife will also not allow you to have a big AVR and speakers.
Then we bought the JBL 1300 had auditioned Bose lifestyle 650 but JBL was better and at a much lesser price. Bought it for 1.35 Lakhs at that time. It is a good sound bar with truly wireless rear speakers operated using inbuilt batteries compared to powered adapters to be used with Bose. It supports dolby atmos surround is good, the 10 inch wireless subwoofer is decent but you will not get the trues atmos or even 5.1 feel that I get compared to my Onkyo HTR-393 receiver. All the sound comes from the center which the most major drawback of a sound bar. Otherwise it is good. But I wonder if there is any benefit of buying the 1300 model over the 800 or just the normal 5.1 model with wireless speakers and wireless subwoofer. The subwoofer is the same in all of them. The atmos effect is hardly felt though it is actually there but you have to elevate your consciousness to understand that. The surround speakers can be attached one sides of the sound bar making it one unit when not in use. They still work and keep getting charged. They can be used as separate bluetooth speakers as well but the quality will be just like a small satellite speaker. Two surrounds can be paired together also ti get stereo effect. They can also be attached to each other to create a mini sound bar. The 1300 model does not come with a side cover for the sound bar when the surrounds are removed from it but other models have a plastic cover which you can put on the sound bar when surround speakers are in use separately.
All that said it is better to go with AVR and speakers. Marantz Cinema 60 AVR (approx 105000) with Taga Harmony 506 or 606 speakers package (30000-50000) plus Taga 807 bookshelf speaker with a 12 inch subwoofer shall be within you budget. You can also go for QAcoustics satellite speaker package with comes with subwoofer (approx 30000-35000 including subwoofer)
