OP here, I ended up purchasing one USI MI106S, which advertises the following:

• Combines the benefits of both Photoelectric & Ionization technology in one alarm
• Smart Alarm Technology virtually eliminates nuisance alarms
• Automatic temperature and humidity compensation continuously adjusts to variations in environmental conditions, reducing nuisance alarms

Which sounds like what I’m looking for. I’ll try some informal tests on it before I buy more.
