I am trying to find a suitable pannier rack for my Cube Cross Race, but due to weirdly placed eyelets I can't find any.
Can you recommend any that would fit?
The eyelets on this bike are not made for pannier racks. Their intended use is to mount fenders, so they are probably not built to withstand the loads of a full rack. So unfortunately I suspect that the answer to your question is: "there is none". But you can go with bikepacking-style seatpost bags if they fit your use-case (which is what I do).
Source: I own almost the same bike (different model year and higher-level components, but same frame).
Edit: Won’t work for your bike. As Paul and Andreas pointed out in the comments your bike has thru-axles and not QR axles.
Tubus offers an adapter for Quick Release axles. Since you have a mounting hole in the seat stay bridge you could use a rack like the Tubus Fly Classic. I’m not sure if the QR adapter is compatible with non-Tubus rear racks.
Trek also offers a rack complete with adapters: https://www.trekbikes.com/gb/en_GB/equipment/cycling-accessories/bike-racks-mudguards-locks/bike-racks/bontrager-backrack-lightweight/p/08214/
