Can we also use the perfect future in both situations instead of either condicional simple or condicional perfecto?

I miss the rationale behind this. is this something to learn 'by heart'? as in, just learn these exceptions and you're good to go?... or is there some reasoning, eg. that without the accent it would be pronounced wrong.. this because of ?

When do you use qué and when Cuál?

As per what I understood qué translates to what whereas Cuál translates to what or which. 

Then , in the starting line, why can't it be Cuál... as in "Which (food) do you like...?"

On another course, an example conversation between novio and novia goes: “usted sabe que lo amo. Vayamos al cine, hay una película nueva que quiero que veamos. Me muero por que usted la vea”. It was partly my frustration that there was no explanation of the use of usted here that led me to look for another course. Can anyone here explain this to me? Is this a regional peculiarity? Maybe Colombia? Thanks.

What is the translation of this sentence 'Nunca hubiese pensado que mi destino estuviese en Cantabria'. 

Could it also be Nunca hubiese pensado que mi destino estaría en Cantabria? Or does this change the meaning?

Many thanks,
