I've used these before from Amphenol/Telaire: https://www.amphenol-sensors.com/en/telaire/co2/525-co2-sensor-modules/3215-t6700 https://www.amphenol-sensors.com/en/telaire/co2/525-co2-sens... I think they're around 60 bucks (e.g. the T6793) so they aren't the cheapest around, but they're good quality. They have a normal header you can solder a few wires into. Probably the best approach for the Sensirion sensor is to oversize the pads a bit and use paste to re-flow underneath.

I have quite a few of the older T6613/T6615 sensors that I got when Newark was selling them for like $10 a piece. The way I soldered the SCD41 is with a pre-made PCB footprint, some solder paste and a mini PCB heater. I think the problem was too high heat. I need to try it again with low-temperature solder paste. But for my application the Senseair Sunrise looks a lot better.
