It can point you in a direction, for sure, but sometimes you find out much later that it's a dead-end.
AFAIK, IPv6 does not truely address the router memory concern. With so many more addresses and more bytes-per-address in the tables, i imagine it's only a matter of time till we are back to such fundamental woes as "where does this packet go"... but i suppose that is limited by the rate that people buy and move ipv6 address blocks.
Given the image, I first thought it was a sci-fi planet.

This is worse than a boring distopia. This is a "let's scientifically measure and control the breaking point of humans" level distopia.

TrueNAS scale helps a lot, as it makes many popular apps just a few clicks away. Or for more power-users, stuff like the linux cockpit also really helps.
To directly answer your questions...
- In the event of DB corruption (which hasn't happened to me yet) I would probably rollback that app to the previous snapshot. I suspect that TrueNAS having ZFS as an underlayment may help in this regard, as it actually detects bitrot and bitflips, which may be the underlying cause of such corruption.
- In the case where a device breaks... if it's a hard drive that broke, I just pop in a new one and add it to the degraded mirror set. If it's "something else" that broke, my plan is to pop one of the mirror shards into a spare PoS computer (as truenas scale runs on common x86 hardware) and deal with the ugly-factor until I repair or replace the bigger issue.
- The only way to defend against a cloud provider is replication, so plan accordingly if that is a concern.
- If by "sync'd confidentially" you mean encrypted in transit, I'm pretty sure that TrueNAS has built in replication over SSH. If you meant TNO, then you probably want to build your setup over a cryfs filesystem so no cleartext bits hit the cloud, although on second thought... it's not really meant for multi-master synchronization... my case just happens to fit it (only one device writes)... so there is probably a better choice for this.
- Setup is a hassle? Yes... just be sure that you invest that hassle into something permanent, if not something like a TrueNAS configuration (where the config gets carried along for the ride with the data) then maybe something like ansible scripts (which is machine-readable documentation). Depending on your organization skills, even hand-written notes or making your own "meta" software packages (with only dependencies & install scripts) might work. What you don't want to do is manually tweak a linux install, and then forget what is "special" about that server or what is relying on it.
- How safe is my setup? Depends... I still need to start rotating a mirror shard as an offsite backup, so not very robust against a site disaster; Security-wise... I've got a lot of private bits, and it works for my needs... as far as I know :)
- Still enthusiastic? I try to see everything as both temporary and a work-in-progress. This can be good in ways because nothing has to be perfect, but can be bad in ways that my setup at any given time is an ugly amalgamation of different experimental ideas that may or may not survive the next "iteration". For example, I still have centos 7 & python 2 stuff that needs to be migrated or obsoleted.
This is the experience of a senior developer using genai. A junior or non-dev might not leave the "AI is magic" high until they have a repo full of garbage that doesn't work.
