Play the "Stronghold" map. I'll say right away that this is my map. I don't want to brag, but judging by the description of what you don't like, all of this is absent on my map. It has strong garrisons and so on.
I recommend playing as the blue or green player, or maybe the yellow one. I don't recommend playing as the red one because, in terms of design, its territory isn't very beautiful.

In general, a dynamic game with player interaction is more interesting, in my opinion, than spending a month or two building up, and then using the "total clearing" method to crush everyone. But again, it's "a matter of taste..."
The way I play... I take three or four bottles of Spaten, sit down, and get twice the enjoyment. So, wild dynamics and a hurricane aren't my thing. But again, I agree – it's a matter of taste.
