I might get in trouble for saying this on this channel ;) - BUT - If memory serves, Proxmox has native support for backing up to an AWS S3 bucket. I think I paid something like $3/month for it when it was setup - very minimal. While not really "self hosting", I would argue backups are the one thing you should actually do offsite, ideally with some resiliency.
Honestly, OPNSense has some fairly decent reporting that can take you a fair ways. https://docs.opnsense.org/manual/reporting_traffic.html
Watching the traffic in those tools can highlight a lot of concerns. Is outbound wide open from all networks?
In general, I wouldn't recommend doing auth at the network layer. You could do radius, AD, or something similar if that's a concern. You could use Tailscale and create a mesh overlay - I'd do that before VPN. Going down this road can, of course, cause a lot of challenges with phones and other iot devices. I tend to keep the iot vlan barebones for that reason.
I've honestly had decent luck with APC but also ran a lot of Tripp Lite. Eaton is decent. Using their calculator, this model (https://www.eaton.com/us/en-us/skuPage.5S1500LCD.html) would run for 71 minutes on a 100W load. It's going to be hard to get below $300 for an hour of runtime. You're going to want to target 1000VA or above.

Agree with all the comments here - old iPads make a great dashboard for Home Assistant (and most other home automation systems). If you want to wall mount it there are several vendors that offer surface or flush mount. Get yourself a poe to usb convertor and you're done.
