That's pretty much the only move for Springer at this point. The Jays have two more seasons of him, so let's hope maybe he has a rejuvenated season offensively where he can provide 2 WAR.
Tough to come up with a list of trade partners given his regression, age and contract. As well, that team would need an outfielder.
Nolan Arenado perhaps, but doubt the Cards move him straight up for Springer. Would be nice since he would fill in the void at 3B and has posted a 2.8 WAR season thus far. He's under contract until 2027, so an extra year longer than Springer.
Trevor Story, but the dude is made of glass and under control until 2028. Plus the Red Sox outfield looks crowded as is. Would rather have Springer for the two remaining years instead of 4 years of Story anyways.
As for pitchers, not many that I could think of. Robbie Ray would be interesting (has an opt-out after 2024 but doubt he uses it). $24.33M AAV over the next two seasons, so identical to Springer. Not sure if the Giants want a veteran OF bat however. Yu Darvish is under control until 2028 with an AAV of $18M, though again not sure if the Padres need another OF.
