To make things even more compact, I also moved to the Sensirion SHT4x line of temperature/humidity sensors, specifically the SHT45 which is the most accurate one available. While I could have stuck with the Bosch BME280 line, I ultimately found that atmospheric pressure wasn't all that useful on a room-by-room basis (and because I got a proper Ecowitt weather station for that instead), and I found that actually finding BM*E*280's versus BMP280's was incredibly hard due to constant mislabelling on AliExpress, Amazon, and elsewhere. Using two GY-form-factor sensors also let me make a much more compact sensor as mentioned below.
I was actually so happy with these sensors that I even went so far as to design a "micro" air quality sensor using just the SGP41 and SHT45, along with an ESP32-C3, for use in other places like my 3D printer exhaust filter and my server rack.
