You’re right, for new drives it looks like a little more with this 20GB retailing for $230, or $11.50/TB.
For refurbished, I recently got a factory renewed 12TB Seagate for $112 ($9.33/TB), but that price is now up to $199 for the same drive (!).

About 4.4TB, but that’s all architectures and (I believe?) all distributions (stable, testing…).
If you only want source+all+amd64+arm64, and only want stable, it will be smaller of course.
Not nothing, but at $10/TB or so, it’s not much.
And if you’re following 3-2-1, I’m pretty sure the “1” is already handled for you :)
I’ve been really impressed with Immich, can’t recommend it enough.
I’d put substitute first, but yours sounds better :)
(I’m a big Immich fan, and I’m taking and sharing photos more than ever before, in part because Immich is awesome, self hosted, and open source [the other part is that I have kids now so I’m taking way more photos that grandparents want to see].)
Physics is like sex: sure, it may give some practical results, but that’s not why we do it.

I think the same is true for a lot of folks and self hosting. Sure, having data in our own hands is great, and yes avoiding vendor lock-in is nice. But at the end of the day, it’s nice to have computers seem “fun” again.
At least, that’s my perspective.
Regarding DNS servers, what router do you have? Some routers have simple enough DNS capabilities — I have a MikroTik, and have it set up with DNS entries for internal services (including wildcard). Publicly accessible services just use my registrar’s DNS (namecheap — no complaints).
