I see...I too enjoy a slower game of maneuvering, akin to chess.

But the pause button? No way man. Might as well have your mommy bring you milk and cookies while the AI does their turns
The only way I know to slow the game is the pause button, you can increase speed and decrease it but by default it starts at 1.0.

I enjoy pausing and issuing orders at the start, then seeing where things go from there.

Some people enjoy to just skip deployment and not even pause to issue orders, just push it forward in real time from go.

I prefer though the speech, the deployment, then issuing orders and watching it play out. Then I can always hit pause again if need or play the rest in real time.

It's one of the joys of Total War over other RTS, it's turn based and real time :) everyone happy.
