Does the vinyl plank you installing already have underlayment on it?

Concerning the product waterproof floating vinyl plank or tile floor, it will not leak to the subfloor - by the same token, condensation from the concrete will not rise through the seams.

I want to keep the room as comfortable as possible. The concrete was poured in the 50's it's far from laser level. I figured the thermal break and the extra padding would help not to mention sound deadening.

Most manufacturers recommend pouring a leveling compound first in order to prep the floor. if there is too much deviation, it will cause the joints of the planks to separate over time and ruin the floor.
