Unfortunately the AC-130 and A-10 aren't survivable against any sort of serious aid defense system. They won't be flying over you if they get shot down by a SAM on the way there. This is the main reason the JSF program was started in 1993 and the problem has only become more severe since then.
F-35 barely has a shot against modern layered Russian air defense. It’s not stealthy enough, counting on engaging beyond the range of air defense abilities to respond is iffy, considering the range of the AGM-88G and the Russian S-400 and one would assume the S-500 is better but who knows.
The expense and rarity of the F-35 only exacerbates this problem, you can’t afford to dangle them in front of air defense so they turn their radar on, you could loose the plane.
Better luck to be had by spotting air defense from satellites and launching cruise missiles or stealthy drones.
I don’t see a place for the F-35. To fat to dog fight, to expensive, fast, and too limited in weapons stores for real CAS missions, too expensive to keep running in the numbers we would need for an actual great powers war. Barely made sense in 1993, it really really doesn’t make sense in the modern battlefield today.
In any major near-peer conflict our reconnaissance satellites will be the first casualties. Don't count on having those available to spot air defenses.
Obviously an F-35 won't be sent in alone to perform CAS in a high-threat environment (unless the situation is really desperate). But it's at least somewhat survivable. Those legacy platforms aren't survivable at all if the adversary has even basic air defenses.
Once the “destroying satellite” line was crossed (and associated Kessler syndrome destruction that would bring to the world) I can’t imagine a nuclear ICBM exchange wouldn’t be next. So I suppose none of those planes matter
Based on what’s happening in Ukraine, I suspect any airplane is basically just a lift platform for missiles. They’ll be fired off well behind the front where established air defenses can counter enemy air defenses.
