Looks to me as though the X wing on 8 and the XYZ on 569 are both
single shots.....

As an alternative, from the same starting point, there is an XY chain starting at r1c9 which eliminates the 5 from r7c9 thus:

If r1c9 = 5 then r7c9<>5 AND
If r1c9 = 4 then r1c3=2 so r9c3=9 so r9c9=5 so r7c9<>5

THis forces r7c8 = 8 which solves the puzzle.
