There are some quirks in the system that can be exploited.
First, there is no real concept of combined arms. So you can build very tank heavy stacks - say 3 British armoured divisions each with 3 attached armoured brigades - to no ill-effect. In reality that would have the problem of the Soviet 1941 Tank Division ToE of too many tanks and too few supporting units.
So if you ignore some of the obvious terrain issues such as the malus for armour in dense terrain or the bonus for Mtn units in mountains etc, the key is bigger is better.
Second, if an essentially motorised/armour stack attacks and wins against non-mot infantry the post battle losses escalate. If the recipient is low morale/experience/ToE this can escalate to a rout. Less common in WiTW than in WiTE but it does happen. Also if the defenders are regiments they are more vulnerable to an armoured attack than may appear from the notional cv.
So to answer your second question, yes there is an advantage to using your tanks vs infantry (if you can avoid entrenchments or restricted terrain).
To the first, you probably need to - as above you can build much bigger CV stacks with armour than with infantry so if you really need to attack a large armour based defensive stack then you need to use your armour.
In this sort of situation it can be very instructive post battle to look at what was engaged/lost/did the damage. While you have little control of the ToE below the unit counter level, you can use your support units to move key assets around.
Now I think the real question is why are you attacking the defender where they are strong? Realise at times you have no choice but in general the game system rewards finding and exploiting a weak spot. Sometimes that involves creative use of your air power to generate these circumstances. If you are the axis, I can't think of many times I'd want to attack into a position of strength, mostly your attacks should be designed to beat up an over-extended unit so you are looking for vulnerability?
Edit: I think the key advantage of armour in all the WiT... series is not its combat power but its mobility, if you have to use your tanks to make the assault you are surrendering that mobility - and, of course, there are times when you need to do just this
