Best Match/Best Synergy?

any standard 14AWG cable will do. Just a decently built one that has the terminations you want, banana cables or otherwise @erastof 

I’d say get two of this - https://www.amazon.com/GearIT-Premium-Braided-Speaker-Plated/dp/B0713ZJDFG/ in either white or black at 10ft (leading to roughly 20ft distance between the two but surely you’d not have the speakers that far apart so the extra is just for ease of droop) 

any standard 14AWG cable will do.

No.  Just…no.  First, what cables/interconnects are you using now, what’s the rest of your equipment, and what improvements/sound characteristics are you looking for?  And what’s your budget and are you looking for new or used?

+1 on what @soix said.

Well if your budget is under $20 I think the Amazon cables look pretty.

Otherwise, +1 on what @soix said! 

Those Amazon cables have a prominent red banner that says "frequently returned". If the price wasn't a big red flag for you they put a literal one...

Yup. What’s in dah house going with the Borresen 02? With speakers like the Borresen 02‘s most here would be assuming budget is very healthy. 

Original poster: "I have speakers costing roughly what a nice BMW sells for, what cables should I use?"

Typical forum cable anti-enthusiast: "I recommend this no-name $20 junk, that's all you could possibly need". 

+1 @996turbo911 !  

@erastof  -  To get the back on topic of the original question... lol....

There are a lots and lots of possibilities, as I'm sure you have guessed. 

That said, as @soix mentioned, it really would help if you posted what the rest of your system is and, prehaps most importantly, what your budget is.  (and how long do the cables need to be...)

Agreed with the post above me. There are a lot of great cable brands out there along with some I don't care for all that much. I can't make an accurate suggestion without knowing more details about the setup, the budget, the goals, and that sort of thing.

@erastof 

I think speaker cables have interactions with both the speaker and the amplifier, so it is a mistake to think about the best fit without considering both.  The cable can present, along with the speaker a combined resistive or inductive load that your amplifier is not happy with,.or at least is not a great match for.  For instance, a tube amp might sound great with one cable, while a SS amp needs another.  But it is much more fine-grained than that.  What you seek is a great amp>cable>speaker combination.

Audience Cables - the best ones you can afford. I use AU24 all around and they are terrific in my setup. I went from Transparaent to Audience and have been happy with these speaker lines, RCAs and Coax cable for several years.
Just my opinion...
