I’ve been reading a novel where one of the kingdoms is one of this super high-tech magic nations with sort of pseudo-modern technology based on magical engineering.
I’d really love a story like that, or to build such a kingdom myself if I got isekaid.

But I think an interesting background for one could be like a sort of Atlantis style one, but with their advanced technology they spread their hegemony far and wide!
Only to collapse or regret their atrocities and go into isolationism.
Then a hundred years later or so they begin to reach out to the backwards cilvizations left on the foreign lands they once conquered.
