I guess what I'm asking is does it need to be hand-solderable? With places like JLCPCB offering cheap SMD assembly, SMD boards are still accessible to hobbyists.
I though JLPCB only assembled components that are available in their catalogue. If they don't have the part you need, you'll have to hand assemble it. These are pretty niche components, with odd footprints and size so I'd be surprised if assembly was available.
You can have them order parts that are available at Mouser, Digikey and the other parts vendors. They have the SCD41 [0], SGP41 [1] and a variety of ESP32 modules (e.g. [2]) in their catalogue. The preorder prices can be a bit out of whack but they'll correct them when they actually buy the part.
