How does one actually prewire cables *in* the central location? - eviltoast

Two questions! End goal is to have a small rack in the closet with the cables hooking to the patch panel. There’s a mix of fiber, RG6, and CAT6. Service is RG6 for 1200/45 (included for completion).

For starters, I’ve got almost all my runs done (not all are in the second picture, it’s outdated but it’s just more loops), but I have no idea what to do with them until the drywall goes up. I was considering a network enclosure, but there just isn’t enough space in the stud section I pulled them through. I have 3-gang lv boxes… skimmed that someone had used them but there was no example and I can’t visualize it.

Second, electricians turned the house into a spider web of electric runs. There’s zero chance of all of my runs meeting at 90 degrees. They also ran a RG6 drop to the closet through a cable raceway that has a lot of their electric runs (a few 110 and a 220). Essentially, how *actually* bad are close parallel runs with RG6 and unshielded CAT6 and electric? I’d really rather not rerun what’s been done, but if it’ll be a noticable quality decrease I won’t have too much of a choice.
