I think we need to keep in mind that the QE's are not meant to replicate the Nimitz/Ford CVN's in either role or capacity.
Better to think of them as upgraded "thru deck cruisers" - I do have a horrible worry that this distinction may "go missing" with the passage of time and there'll be repeat of the WW1 "Battle Cruisers are as good as Battleships" disaster
The UK can't afford all the bells and whistles so there will be (necessary) adjustments and lack of capability cp the USN vessels
