Got an Elite Suito T (it was cheap-ish and available), the indexing is a bit off compared to my wheel, any thin approx 0.2 mm shims available that fits shimano 11 spd freehubs?

Shimano HT2 BB shims.

Hmm I measured the distance from the frame to the smallest sprocket on the turbo on with the wheel installed, the sprocket on the suito cassette (R5800 11-28) is exactly 1 mm closer to the frame than on the bike (R7000 11-32) - so I would have to shim the bike cassette to get closer which I don't really like as it degrades the chainline in the smallest sprocket..

Or could it be the cassettes that are different.. lengths?

A dedicated turbo bike is the only real solution 😃.

The cassettes are the same length about 40 mm not including the lockrings, but the length from the seat of the freehub body to axle hole was 1 mm shorter on the Suito, so I need to find a 16 mm ID 22 MM OD 1 mm thick shim that extends the drive side

If you know how much it is out by then readjusting the shifting each time you change wheel/trainer should be childs play.

12mm or qr? You could shim the drive side by 1mm rather than the cassette.

12 mm, yes going to shim the axle on the trainer (there's a thru axle adapter that screws into it, it can be shimmed w a 1 mm spacer) - something like this

If you know the exact dimensions, I can machine you one.

I need something to do while my CNC lathe munches it's way through a few lengths of bar this week.

I’ve had the same/ similar problem with my elite zumo although my sram 11 spd cassette wouldn’t cinch together without a spacer but with the spacer indexing was out! I gave up and bought some mudguards!
