While it's true that the Season 11 comics covered what was basically the year after Clark's debut, and while I agree with you that Smallville Clark had been Superman for about a decade at the time of the Crisis Crossover — from 2011 (his debut year) until 2019 (the crossover) — I have my doubts about the newspaper articles being connected to the Season 11 comics. They're mostly homages to Donnerverse/Returns headlines, which is in keeping with Smallville's habit of homaging their predecessors and peers. the "CAPED WONDER" headline is from Superman I, the "I SPENT THE NIGHT WITH SUPERMAN" is from Superman Returns, and the "SUPERMAN SAVES THE DAY!" is from Smallville's 2017 flashforward from their 200th episode "Homecoming." Yep. SV Clark lived in a world filled with other heroes.
