AFAIK, he never opposed such laws, but I've never seen any evidence he promoted them.
Even Lincoln wanted free blacks to remain out of Illinois.
Again, I am unaware of his publicly opposing such laws, but also of any evidence he "wanted" them.
Even Lincoln’s first inaugural address he claimed he had no intention of interfering with slavery.
Flatly untrue. He stated he had no intention of interfering with slavery "within a state." He had every intention of interfering with it in the territories and in DC, where he had constitutional power to propose interference.
In fact, Lincoln, during his single term in Congress, proposed a bill "interfering" with slavery in DC. In 1849!

Something I've never seen mentioned is that Congress could have entirely constitutionally passed a law prohibiting interstate traffic in slaves, even between slave states. Which would have put a real crimp in the market and constituted big-time interference.
Furthermore, the Constitution forbids “Corruption of the blood” which would reasonably free any child of a slave until they had committed some offense personally.
