The cabin is a bit wider than standard a320. They advertise 18" wide seats. If they are 32" apart that's ok. It can even fit lie flat business class seats. And if it means flying direct instead of changing planes in a busy overcrowded airport and having to lose time waiting and queuing (and "saving the planet") that's pretty appealing
The A321 is not wider than an A320. The A320 family[1] comes in a variety of sizes and configurations to support different profiles, but they are all variations in length, fuel capacity and MTOW.
Making a plane longer is relatively straightforward, just insert additional sections before or after the wings. Making a plane wider you may as well design a whole new aeroplane.
I said "cabin is a bit wider" not the plane itself. I was under the impression that with neo they made the isolation on the walls of the cabin a bit thinner (2 inches?) gaining more room in the cabin while keeping the outside shape the same but I can't find anything about it anymore

That is the most important thing imo. A 6 or 7 hour flight to your destination is so much better that the same length to Frankfurt or wherever and then waiting and taking another 1-2 hour flight somewhere. Most of the pain with flying, except maybe of ultra long-haul, is what goes on before take off and after landing. If you only have to go though that once, it's a big deal.
Plus, I dont see any material difference in comfort between modern wide and narrow body, other than your less likely to be stuck in a middle seat on a narrow plane and they board faster.
