You aren't wrong. 100%, it's an MCU movie and MCU movie is gonna MCU movie.
Out of universe, that is absolutely the correct answer.
I prefer to look at things from an in-universe perspective and understand why things are the way they are, and I think I made at least a reasonable argument. My proposal does fit in with the established lore. The tl;dr version: Wakanda is stifled by adherence to tradition, they've never been tested by an outside power (until Talocan), and their entire military doctrine is based around defensive turtling, infiltration and misdirection. We also know from "What If" that once Wakanda is broken free from it's tradition, it... IS a 5th generation warfare powerhouse.
I'm by no means a milnerd... I actually tend to not like things that get too miltary..ey. I'm not looking for a hard sci-fi super realistic depiction of advanced warfare. I'm looking for... dudes with laser guns.
I'd like to see the next Black Panther movie be somewhere between "Stab people with spears" and the stuff you posted... and to be honest, i'm pretty sure that's what will happen. Shuri Panther already uses her ranged sonic weaponry, the Midnight Angels have been introduced, and with Shuri has been outspoken about not particularly caring about tradition.
Wakanda is going to be absolutely scary under Shuri. And that's awesome. I thought Wakanda Forever was just an ok movie that tried to do too many things, but i'm honestly super hyped about what it set the stage for. It doesn't need to (and won't) happen the way I suggested, with like a US invasion of Wakanda or something. The movies already laid out the framework for it happen organically. Wakanda already got absolutely smacked by Talocan.
To tangent off, Talocan is also just a completely out-of-context issue for the world at large. Nobody, save for Wakanda, would even have a way to go on any sort of offensive. By the same token, any war Talocan might fight is going to generally constricted to coasts and waterways. Talocan may as well be on another planet.
