Can you recommend a more efficient alternative that is reasonably hobbyist-friendly?

not sure about wifi, but for BLE I think people generally use nRF controllers, there are modules with builtin antenna that you can use directly and are not too expensive.

Something with camera and wifi that costs $6 (like esp32-cam)
