recomendations please - RCA's/Speaker cables for Supernait3 from Node?

Hi, have a budget of 1k for a pair of speaker cables and RCA's, using basic bluejeans speaker wire at the moment and entry level RCA's from Signal Cable

I've been told the Supernait3 is finicky with cables.

Is the NACA5 speaker wire best for my application?  I don't seem to have a local vendor for these, would need to go to ebay

I was previously using Analysis Plus Oval 12 which I love but does not have bananas

I have no idea on RCA's, so many choices,
