It all depends on where IN's priority lies. If they want commonality, they will go for a 60000+ t STOBAR carrier, similar to IAC 1, take additional N-LCAs or Mig 29Ks until N-FGFA will be ready.
That maximise common training, weapons, systems and spares, with the most capable carrier fighter as well.
However, for the best carrier operations they need catapults, which means they have to take completelly new fighters without commonality (no Rafale M doesn't mean commonality, because IN don't operate it or it's system on another carrier, so has no experience with it).
The Super Hornet makes only sense with upgrades, be it additional senors and if possible more thrust, but most important will be the CFTs and the weapon pod. Since that will give it a clear advantage against most non stealth fighters. In operational terms the SH might also be less effected by restrictions than the F35 and that should make it easier to operate it for IN, not to mention the more reasonable costs.
The long term solution however must be a naval AMCA and it's worrisome how less importance IN, MoD, or even ADA/DRDO/HAL gives it!
Not in future, but as soon as it's available! The 737 platform is not designed for low altitude ASW attacks, which is why such operations will effect the life of the airframe. That's why the USN wanted such developments, to make the launch of torpedos possible from high altitides, or why they didn't opted for the MAD (afaik the Australians neither).
