I haven't found details on linksys ax6000 but the rax120 looks good on specs and no bugs on github so I would go for it even if there are stable builds just yet - snapshots are good for beginners as well
Looks like there is no ath11k on the wlan driver dropdown box and someone picked the wrong one. Just corrected it also fixed a few other specs while I was in there. The DL-WRX36 was wrong the same way just fixed that one too.
