Sensor fusion is something that any 4.5 gen fighter is capable of. Cool HUDs and XR is just marketing bling. It doesn't really matter. Scale, sensors, ew, range, load and cost benefit matter.
F-35 is good if you need first strike tactical nuke capabilities today. Or small carrier capabilities. However, modern sensors can probably catch your F-35s quite early on anyway. The extra stealth might be good if you're fighting goat herders with Soviet AA and radars from the 50s. But hey, then you can just go for an upgraded F-16 with some fancy EW.
Any rational state actor should skip 5th gen, push their 4.5s to the limit and go for unmanned gen 6+.
