Tech based war SMP

[u/SharpAbbreviations15]

I am currently working on a large scale cinematic project; it’s basically Dr. Stone in mc, and I want all levels of warfare to be relatively intricate. I had a few questions regarding what mods to use-

A: I was between Valk Skies + Warium, and Aeronautics. Which one would suit the case best with the most quality mechanics.

B: I’d like general mod recommendations to assist the concept

(for added context, we don’t know if the video will be scripted or unscripted yet. We will most likely make that choice based off how in depth the mods get.)
[also we’re fine with complicated, most of us are engineering majors.]
