Wait, what's wrong with the Q&A? Why wouldn't the players want to know the size of the room and how big the obstructions are, etc?
What's wrong with it? Nothing. What don't I like about it? Plenty.
Ideally the size of the room and the basic scope of options are described by the DM in Step 1. In Step 2, the players can describe their characters as doing something to get additional information they need. The DM can then, in Step 3, narrate the result of that. (Repeat.)
In my experience, if the players are asking a lot of questions, there are likely two things going on: (1) The DM is not providing enough context in the description of the environment for the players to make informed decisions or (2) The players are seeking pre-approval on their actions before taking them as a form of failure mitigation.
The end result is that the players are having a conversation with the DM rather than the player establishing what the character is doing and potentially identifying with the character more easily which appears to be the OP's goal.
