There are materials resistant to laser swords and the magic in general in the EU. It's an important factor in Hand of Thrawn I think.

One thing you haven't mentioned is real-time intra-galactic video calls.

The government(s) is comparably effective to modern governments here on earth, which is to say rather dysfunctional. This would be more impressive if communication was limited to FTL couriers, but it's very much better than that.

Spycraft isn't too effective against members of the government using the government to destroy the government. It's a problem we haven't solved either, at least in democracies. The government is also not a major force everywhere in the galaxy, and a lot of spycraft and intelligence went into rooting out dissenters. It's basically the whole plot of Episodes IV & V.

I think droids that are capable and/or willing to engage with subterfuge at more than face value are both expensive and controlled. This moreso exposes how relatively widespread and easily obtainable high-level computing is, yet it's mostly slept on. There might have been an AI war at some point in the past that causes people to take AI shackles very seriously, but that brings us back to having large numbers of populated worlds without significant government regulation of any kind. AGI is a real weird point in general here, I agree.

There's lots of capital ship battles, especially in the EU. The originals don't have a lot of them because the Empire took them all and keeps a tight fist on everyone capable of making them, while the prequels are about the escalation of a very peaceful government to war. I think Clone Wars stories have more of this. Asymmetric warfare is definitely a thing in the main trilogies though, unless I misunderstand what asymmetric warfare is.

Weak points? Absolutely. It's a disgrace to engineers everywhere, to the point that the Death Star's flaw has been made into an intentional sabotage in at least one story.

I'd really like to see more laser sword tech though. Like Grievous but on purpose, maybe large plasma tunnel bores or something.
