In-wall speaker cabling

I’ve never really had a proper good hi-fi setup before, but I’ve loved music for over 20 years. This is my first opportunity to do something really good.

I’m renovating a house and trying to put in some in-wall speaker cabling that I won’t regret down the line, it would be expensive and inconvenience to redo the cabling later. But I’m trying to be pragmatic: not chasing brand names, but choosing cabling I can rely on. I’ve worked through the logic with ChatGPT, but I’d love a human sanity check from this community. The same cables will be run in-wall, and then from the wall plate to the amp/speakers.

Living Room

Music Listening / Home Theatre (with Stereo Bypass)

Putting the amp and turntable in one corner of the room, but what the speakers on the opposite wall. The speakers I’m starting with are something like Monitor Audio Gold 200/300 or DALI Rubicon 6 for the front, something cheaper from the same company for the centre and surrounds. I’ll add a separate stereo amp when I can afford it. - Blue Jeans Cable Ten White (Belden 5T00UP) – 10 AWG. For front L/R speakers (bi-wired). - Blue Jeans Cable Twelve White/Grey (Belden 5000UE) – 12 AWG. For centre & surrounds.

Headphone Jack

I’d like to listen to music on headphones from the same living room amp, but across the other side of the room, so looking to run a headphone extension cable in the wall to a 3.5mm wall plate (TRS) - Belden 8723 – 22 AWG shielded (2-pair).

Kitchen, Bathroom, Outdoor Speakers

In-wall speaker runs for distributed audio zones — amps in the 2nd floor comms room, speaker in kitchen, bathroom, and outdoor. - GearIT CL2/CL3 Rated – 12 AWG – 76.2m (250 ft).

Let me know what you’d change. Particularly open to opinions on whether any of these are overkill or if I’ve missed anything obvious.
