Do you have a list of devices you use? It would be very helpful, since HomeAssistant has hundreds of integrations, and it's a lot of work to track down devices that -

- FAIL NORMAL - WORK OFFLINE - YOU CAN STILL BUY

I really want my smart home devices to meet these criteria, but at the same time I have a bunch of other stuff I do.... so it would be awesome to have a starting point from people who have done it already.

Mozilla used to have such a database, but seems to have forgotten it.

"Work offline" and "You can still buy" are satisfied by looking for Zigbee, Zwave, or Thread/Matter based devices. These don't connect to the internet by design and require an inexpensive dongle to form a mesh network. In very few cases WiFi devices with local HTTP API or MQTT are perfectly fine as well, a good criteria to look at is whether Tasmota or ESPhome (alt firmware) list support for them.

"Fail normal" would be trickier, I don't think there's one size fits all. For lights, prefer switch relays over smart bulbs. Look out for customizable "default" state when power comes back on.
