Piezo harvesting switches and similar (I think there’s a flywheel design out there too) are quite expensive, not terribly reliable or consistent, and require substantial activation force. Conventional switches and batteries that can last for years in remote push buttons and sensors are extremely inexpensive in volume.
The ones I have in my house [0] were not that expensive and have been quite reliable for years now.

Do you know of any where the receiver plugs into an existing outlet and has an inline receptacle for the controlling device already wired up?
That's not really true. We've used these for years to control our Hue lights, and they're fantastic: https://www.amazon.com/dp/B07MMWH2YB
Lmao no, my doorbell is one (doesn't have a battery at) and has been going for 7 years strong, as long as I've lived in this place.
Sure you have to press it very slightly harder than a regular switch and the travel is a little more, but not by much.
I think the doorbell cost like £20 in 2020, actually lemme check Amazon...ah in fact it was 15.99£ (now it's £20.99 hmmm) "TECKNET self powered doorbell".
The Quinetic switches I use are extremely reliable and consistent. I've been mentally making a note of when the switch does not trigger the light, and it actually hasn't happened once yet and I've been using them for about 10 years.
You're right that they're expensive and need a decent activation force. They also are quite large and make a quite loud clicking noise which might be annoying for a sensor application.
