I've been working on something similar recently with a Pi 4B — uninterrupted operation is tricky to get 100% right.
So far, the PiSugar 3 Plus has worked reliably for me. It handles auto-switching, charging, and can trigger a graceful shutdown via software (they offer a service that hooks into systemd).
For “resume exactly where it stopped,” that's tougher — I guess you'd need more than just UPS hardware, maybe an OS-level snapshot/recovery approach. I've been experimenting with a smart home–oriented OS lately that tries to minimize data loss during power events. Still testing how well it handles real interruptions.
Would love to hear what setup others are using too!
