eBike technology explained

Hey everyone!

I'm diving deep into the world of eBikes for my next purchase, and I'm finding the sheer amount of tech out there a bit overwhelming when trying to compare models. Specifically, I'm looking at a commuter eBike for my 15-mile round trip, mixed terrain commute, and I keep seeing terms like "torque sensing," "cadence sensing," "hub drive," and "mid-drive."

Could someone break down the practical differences and benefits of these technologies, especially for someone who wants a smooth, efficient ride without having to constantly fiddle with settings? What's really worth paying extra for in terms of tech for a daily commuter? Thanks in advance for any insights!
