Hifi beginer need help with speaker and sub cables

Hi!

I am beginer in hifi world and i need some spekaer and sub cables. I have some specific requirements for it so hopefully you can help :) Also i was asking come shops or manufacturers for advice and i am getting really different recommendations for what i should select or be careful with choicing the right cables for my system. Hopefully someone here can be realistic and give me good answer or recommendation.

I have amp, speakers and 2 subs, this is the equipment i bought:

Spekers and sub will be placed againts the wall and all the speaker / sub cables will go inwall installed. Each cable have their own plastic pipe (usually used for electricitry installations).

_The max internal diameter of the plastic pipe is 13mm. So I am kinda limited with gauge or cable dimater in this case.

So the lenghs are kinda long so this also give me the limitation wirh my budged.

_I need aprox 13m of lengh for each spekaer / sub.

I am placed in Europe so i have kinda limited access to the cables i can buy here. But if you are recommendin some really good cables worth importing i would also do this but theere will be additional cost with duty/tax.

I was for example looking into following bards for spekaer cable / sub:

I was adviced to look for AWF 12-14 for speakers due to lenght and diameter of the cable for installation.

For subs i did not get any specific recommendation tvh except it should be shielded properly, what ever that really means.

Anyway thank you for advice and help!

Kind regards!
