Partial-home backup: which batteries are more flexible than Powerwall 3?

Unconfirmed: a Reddit user asks Powerwall 3 owners whether they backed up the whole house or only some essential circuits, and how they chose which circuits to prioritize during an outage. They are looking for power for hurricane season, covering a fridge, freezer, Wi-Fi, lights, fans, a window AC in one bedroom, and occasional microwave use. They say the installed price of the PW3 is hard to afford and compare the one-time purchase with their budget. It is an open question; the post provides no pricing, capacity, or equipment specifications.
