recommended speaker cables and interconnects

If your lucky enough to have a dealer near by, try and demo as many as possible in your system. I believe the Cable Company has a demo program.

try to find wires that are OCC single crystal that's the best wire for audio to use, far superior to anything OFC, check out companies like Harmonic technology acoustic Zen their prices are quite a bit cheaper than all the other companies selling OCC single crystal wire and stay away from MIT and transparent because those boxes screw everything up unless your speakers are exactly the right impedance for those wires and they're very overpriced as well.

Well, trust your ears….  I had expensive Chord Company Epic Twin cables and thought they were very good in my system - which they were.   But then I tried GR-Research 24pr cables that blew them away at 25% of the price.    Again this was all in my system and to my ears - but that’s what I cared about.

My advice is to try different cables and see what you and your ears think.   The challenge is the system.   Great cables in one system do not automatically translate into great cables in another system.   It’s the integrate whole that matters to your ears and brain.

As mentioned, Transparent has a house sound that does run a bit through their line. They have good entry level cables all the way up to stratospheric. Shunyata doesn’t quite have the range of low to high, but they too have similarities in the line. Overall, I prefer Shunyata power and speaker cables. I have a bit of a hodge-podge of interconnects each that work well with the given component. You don’t have to spend tons to get great sound, but usually there is worth when moving up a line. It is hard to recommend anything specifically as the answer really lies in the synergy of the whole setup. The only way to figure that out is to try some brands and see what you like.

Notice you received almost as many different recommendations as the number of responses you received.  What does that tell you about alignment and/or agreement between audiophiles on cables?  I will share one more recommendation similar to what you already heard from @mazian, don’t spend your money on cables, at least till you get components and speakers you are happy with.

If you believe you need new cables, then try this cable for ICs (terminate with these or these) and this speaker cable, or this speaker cable, cross-connected and terminated with these or these.  For power cables, try this with these and these connectors.  You could do the whole system without breaking the bank, leaving you plenty to spend on upgrading components and speakers.
