from your list, I would go for the ATart9xi
https://www.audio-technica.com/en-gb/at-art9xi
because it has both very tight channel balance of 0.5 db, and excellent channel separation of 30 db as well as a boron cantilever (the stiffest I will go), and a higher signal output
The tighter the channel balance, the tighter the phantom images that create imaging anywhere between the l/r speakers are, improved distinctness.
wide separation is also a nice way to get more distinction, great imaging for the majority of content.
Sometimes, for too wide (i.e. Bill Evans Live at the Village Vanguard which has a huge hole in the middle)
I use my alternate mc with only 25 db separation (still has tight channel balance)
and/or alter my toe-in to toe-in X, which lets me use my ’too-wide’ cartridge on a non-removable arm.
left speaker aimed toward right listener/right speaker aimed at left listener. you are nearer one speaker, but getting more direct projection from the opposite side. 2 off-center listeners get a stereo image, center and both sides, not too wide.
btw, I went with AT33PTG/II and love it.
