Well, morons bought it and the device is directly connected to a data harvesting company. I think that has more to do with it. One lone weirdo with a hidden camera and a home server isn't the same kind of boogeyman

Probably not your best option, no
A cursory search says somewhere between a 3060 and 4060, which seems about right. Games that parallelize well across the GPU cores will benefit, though that benefit will be niche if it exists at all. HBM2 memory is weird for gaming.
You'd see some benefit for sure, but this really is better suited to parallel computing, given the emphasis on CUDA core counts and memory bandwidth. You may also find you run into some latency, since it requires selecting the V100 as your primary GPU but a secondary card as the video output. Integrated GPUs work well for this, since your motherboard may already have this ability. Otherwise, you could use it in tandem with a 1030 or similar to get display out.
They're actively producing DDR4 and 5, with Corsair notably having purchased supply from CXMT for use in their Vengance line, just not for North American distribution
It's still not bad if you're buying old SAS drives. At this point, anything 4TB or less is fine, and for most people that's plenty to start with.
If you're ripping DVD and BluRay content, you probably will gobble up space quickly without re-encoding it, but otherwise you can store content from streaming services with ease.
Have I gone my whole life doing cover letters "wrong"? I use them as an opportunity to talk about things I've worked on as it relates to the responsibilities of the job that a resume wouldn't necessarily explain in depth. I've never treated it like I'm meant to ingratiate myself to anpotential employer for the chance. Usually the resume is "Here's where I've worked and my roles there" and the cover letter is "Here's what I've worked on and how that experience is relevant"
This isn't the first time you've approached this problem like it's supposedly a relatable aging one. None of the symptoms you describe are things that come with age unless there is an underlying health issue.
