Zwift Cog V2 with SRAM Rival AXS 12 speed

Hi all, complete newbie to Zwift/indoor trainers and just received Wahoo Kickr
with Click & Cog V2 pre-installed.
I’ve got setup and done 3 ‘test rides’ but now I’m trying to fine tune my
Zwift Click & Cog V2 with SRAM Rival AXS 12 speed.
My initial 3 ‘test’ rides although I broke a sweat and did roughly 10mile each time didn’t feel right, messing with the Click, cadence and Watts ERG on or off was weird and I’d started off on the small ring at the front as I’d read that was what you were supposed to do… but pedalling like the clappers cant be right so I’ve moved over to the large ring.
Although I’ve now got the Cog fairly in line there’s still the nagging doubt of something isn’t correct, especially with the Cog number dial, which gear on the SRAM derailleur for a good line-up plus the SRAM AXS eTap micro-tuning faff… all a bit complicated.
Any help or pointers would be greatly appreciated. Many Thanks.
