According to Italian YouTubers, both drivers went for the lower DF rear wing in SQ based on the sector times (S2 in particular) and the top speed :


In FP, both HAM and LEC spared a set of medium tyres, as VER did, saying that this tyre is the favorite tyre for the Sunday race.
Besides that aspect, it was interesting to see how they used tyres during the SQ. Thus, in SQ2, both drivers went for only 1 push lap and 3-lap stint, instead of NOR, PIA, VER, RUS, ANT, who went for a push lap, cool lap strategy doing 5 or 6 laps in the end. That means Ferrari went for a quick warm-up tyre setup, knowing that on the Saturday Sprint race would be a wet/damp race, and this would be a critical aspect in the race.


Then, regarding the Sprint race setup choice, in my point of view, Macca, Merc, and AM went for a dry setup and will use the Sprint race as a testing bed for the main race. Ferrari and VER seem to have a mixed setup, opting for a lower DF setup with a different warm-up phase choice, meaning Ferrari is aiming for a 2-stop strategy race on Sunday, and VER just for a 1-stop one. And last but not least, during the FP, both the Merc driver and VER did a Sunday sim race based on the higher lap times, something that speaks volumes about the Sprint race car setup choice ...
