Good entry level cables

Hi allnewbie here and I am totally confused. Just when i see and decide on a cable, another thread pops up recommending a different one... and I don't have time to keep changing different brand cables around to see what matches or sounds best. I probably only have an mid level system? So I need a consensus (not gonna happen haha) of what I need minimum now and for what piece of equipment.I have what follows- My room is 20x16. Ceiling height is 10'. Equipement is in the rear of the room. So I need speaker cables from FOH to the rear. This is new construction so I can place cables in wall or in ceiling. Probably 30' run of speaker cable. I've looked at monoprice, BJC, and others recommended on here that are REALLY expensive. I'm already over budget lol. Solid core, insulated strands?Power cables?Interconnects?In order of importance. What is the minimum I need? Best for the money?
Equipment as follows:
Atlantic Technologies 8200 - 2 fronts with 2 subs, a center, 2 pair surrounds4 Revel in-ceiling C763L for dolby atmos
Lexicon RV9Sony VPL-vw695es
Audioquest Niagra 1200Lexicon DD8-A for in ceiling revels (not purchased yet for $999 new) Anything better in this price range

With phono cables it is not necessarily getting the lowest capacitance, but the RIGHT capacitance and resistance loading for your cartridge that is the key issue. For really long interconnect runs, say >5m you are way better off going balanced, but if you are not able to, low capacitance is the way to go. Shielding also becomes very important.
Blue Jeans may have high perceived quality, but I‘m afraid that‘s where it ends. I bought a 3m pair to replace my 2m 20yr old DIY pair made from good quality off the reel stock from my local high end audio store because they were no longer long enough for my purposes. The drop off in audio quality was immediately obvious. Dynamics were squashed, and clarity went down two notches. I REALLY wanted to like them and waited ages for them to break in. In the end I just rearranged my equipment back the way it was so I could use my old cables.
I have since moved on up the food chain but still remember the experience clearly.
If you would like to hear their limitations very easily, (I know it‘s unfair but it serves a purpose) put them up against something like a Cardas Golden Reference or a top of the line Nordost. You will get a handle on their sonic signature immediately.
However, you don‘t need to go anywhere near that price point to get clearly audible improvements.
Want to recommend Blue Jeans 10 ga
speaker cable - great quality, very inexpensive. Great entry level cable.
I was referring to their interconnects, I do no have any experience about their speaker cables.
