Is that a lot? That doesn't seem like a lot. I'm an American, our government's insanity gives us a false sense of what constitutes "a lot" in a military context.
I wouldn't say that it's a massive package, but it's part of a steady stream support. However as you say, it is hard rival the US military complex in size.
As someone already mentioned the Iris-T SLM system and radars are probably the highlight. Air defense is always needed and this is a modern system. Ukraine already got 2 of them before and presumably this is a newly produced one. So in this regard we really are limited by supply.
Iris-T is a state of the art medium range air defense system, reportedly with a hit rate in the upper ninety percentages. The Vector drones are also a couple hundred thousand per drone.
They were almost certainly referring to the winter & electricity gear. Unless there's something undisclosed, but I don't see that given that Ukraine still lacks a launch platform for Taurus.
They managed to adapt the Su-24 for Storm Shadow, no reason it couldn't be done for Taurus; they are of similar size and weight.
I think the compromise was that they need to be programmed on the ground, as the aircraft avionics don't offer a compatible complex interface, but a launch signal can be rigged. Since Both will probably be used against fixed targets (airfields, bridges, ...) that is not a big drawback. Still, it needs to be done, and is not quite trivial.
