I think there are very valid reason every Gen 5 fighter has a cannon. I also think neither manned fighters nor tanks are going anywhere soon. The war in Ukraine just painted a fastly wrong picture, for valid reasons for sure, but still wrong concerning modern weapon systems. As long as someone needs something on the ground been blown up from up close, or protect infantry from being blown up frok up close, tanks are your weapon of choice. You want something on the ground blown up from a distance comparatively cheap? Artillery, idealy self propelled for mobility, is your friend. You want to blow up stuff on the ground far away, and fast, you go for fighter aircraft. Or if you don't want to your enemy to do just that, as those are fast, can cover a lot of groind and controlled locally, so no jaming of any kind. If you want to do the same thing from really far away, use a cruise missile. Or in contested airspace where your piloted aircraft are too valuable? Use a drone, same for long endurance surveillance of uncontested airspace.
