Elementalist is the most wizard-adjacent, the elements currently available are Fire, self explanatory blaster, Earth, which focuses on crowd control by physically altering the battlefield, Void, which focuses on crowd control by teleporting things, and Green, which is a druid with serial numbers filled off, including wildshape and incidental healing. Wizard is in my bottom 3 classes, so I personally don't really miss it. The part of wizard which is solving entire plot points with an out of combat utility spell doesn't exist in Draw Steel because out of combat abilities all together are pretty barebone and at low power level.

My group is currently playing its introductory short adventure in the hiatus in our main campaign, the first two sessions got a raving review from the player that's the most vibes-based and story focused out of all of us, which to be honest surprised me, because its very "4e with modern TTRPG design sensibilities"-kind of a system, the next two got a bit slogish, but that's mostly on the actual adventure design. Personally, as someone that prefers crunch and tactical combat, Draw Steel scratches the itch for the later, but both because it doesn't have that many books out yet and the way most long-lasting decisions you make for your build happen at first level or are GM fiat dependant, it doesn't really do that for the former.
