The most capable CAS platform, and one of the most widely used, was the B-1 bomber. Flying in circles for hours and dropping scores of guided bombs.
The best CAS in GWOT would have been the Super Tucano if the program hadn't taken so long. It would have done the same job as A-10 but much cheaper.
The CAS mission is obsolete outside of counterinsurgency. MANPADs mean that going low and slow is a death trap. Getting low and slow was needed in the past to identify targets and make dumb weapons accurate. Now fighters fly at medium altitude for safety and drop guided weapons. Ukraine shows that medium altitude is dangerous with near-peer conflict without air supremacy.
The F-35 is required to gain air supremacy. If you have them, might as well use them for ground support. I think drones will change things with CAS. On one end, can have small attack helicopter drones for direct support. On the other, can have large drone that loiters for long time dropping bombs. The F-35 will be used for things it is good at.
In neer peer conflict air supremacy is probably pipe dream because of combination of ground based anti aircraft systems and inability to take out airports for more than 1-2 hours without using tactical nukes. Tor/S300/S400 and western/Chinese alternatives are highly effective, mobile and hard to detect - you can never take out all of them. AWACS are big, expensive and slow targets so they will have limited utility in a conflict - so limited visibility on what's in the air.
Go low - you will get MANPAD. Go medium - Pantsir will get you. High - S300. Not everytime but often enough that all sorties will have to be very quick with no loitering and unpredictable flight paths (so no CAS).
Drone loitering seems to work really well. We call army units on boats marines. What do we call army units that provide their own air cover? Aerials?
The combat footage out of Ukraine is very enlightening. Communication, drone surveillance, full stomachs and no booze is apparently how you win a land war in Asia.
Yeah good luck getting any long lasting air superiority if you have S400s less than 100-200 miles around. And there are newer models in the pipeline with better reach, although they may be as useful in this decade as Armata.
