An ESP is a chip, not an SBC. So then you have to pick an off the shelf SBC from a different supplier which is either (a) hobby grade, see OP or (b) much more expensive or (c): you have to do your own electrical engineering, component selection, BOM, PCB layout, PCB manufacture, assembly, deal with a contract manufacturer - do EVT, DVT and PVT - ramp production, test/validate, package, stock and distribute the units. (c) is going to delay you 6-12 months.

We also don't know anything about the quality of the software running on those devices. I've seen some awful crimes against computers committed in embedded software - and I've seen some pretty well written software on more capable machines. And v.v. of course.
