I want to use a bike fitted with SRAM Eagle NX groupset on an indoor trainer, and to have a complete wheel including cassette for use on the trainer.

Would it make sense to use another 11 or 12-speed cassette instead of the current PG-1230 cassette ? Is it possible that it won't be as compatible with the chain, and make the ride less smooth ?

At the very least you'll need to match the same cog count to your shifter. In other words, an 11-spd shifter necessitates an 11-spd cog. You don't need to match the level (e.g., NX vs X01). You probably want to stick with the same brand for optimal shifting, but that's a lower priority.
