I figured out the clues
Each trailer is about a child that Dr. Doom will kidnap.
The first being steve roger’s, the second is Love (Thor’s daughter), the third is Cyclops’s daughter and the fourth is Franklin Richards.

There's not much else to lend to a kidnapping story line.
Even then, Love and Nathan are the only powered children currently known in the MCU
