Much better on the info. So, it sounds like you have a decent, good fit, in what should be a good level boot for your size.
So, you are getting hung up on what ankle flex does and 'pressuring the front of the boot'? Talking modern ski design, these skis are designed to have turning by edging engineered into the ski, much more than older ski designs. These skis react significantly more to pressuring changes based on fore/aft shift of the skier's mass and turns are scribed by the radius built into the ski.
So, for most situations, fine weight/mass/pressure control causes significant reactions from the ski. And in many situations, the ski reacts most predictably with the mass/pressure on the ski centered. Yes, a little extra forward pressure in the start of a turn initiates it faster; but exaggeration of pressures will cause unpredictable ski behavior.
"Eliminating' the gaps in the boot shaft fit helps eliminate the dramatic and sudden slamming of the shin into the boot shaft front (tongue) and the subsequent rebound which causes a skier to go into a backseat position/posture. But if you have no gaps, then the eliminator only serves to create a more upright lower leg angle, which may or may not be a good thing.
The combination of foot bed angle in the boot (ramp) and the lower leg angle in the shaft contribute the greatest to your ability to center your mass over the ski and also maintain it at some relaxed, comfortable level. The 'ramp' angle that the boot makes in the binding also affects this. Everything above the lower leg and boot MUST follow in order to create a neutral balance point.
So, if the lower leg is too upright for your body structure/posture, you have 2 options to find a neutral position/posture: A. bend forward more at the ankle (increasingly hard and very tough to do, hard on the shins). B. Lean forward more from the waist - which is really a poor solution and puts skiers out of balance very quickly, with very slow chances for recovery.
So, on a fairly flat trail/run, letting the skis run easily, try to determine if when the pressures at the tongue and the back of the boot shaft are about equal - are you in a balanced, comfortable position ? If Not, then working with the combinations of boot/binding ramp angle, boot footbed ramp angle and boot/lower leg angle is needed to get you into a balanced neutral position.
So let us know whether you have to push against the tongue to feel 'balanced' in flat running or that you might have to lean against the back of the boot to find the balanced position (much less likely). If you do this, we'll have more to consider and discuss.
None of this is intended to make up for actual skiing technique issues or lack of understanding of 'How to' - that all comes AFTER first getting into a neutral position. This is true for all dynamic/sporting efforts/sports.
