Please help :')

I'm looking to get a security camera/floodlight system installed. With the size of my backyard + surface lot situation I'm looking for a pretty strong floodlight/camera with good reach. From what I've gathered from my reddit research thus far, the better route would likely be to get the cameras and floodlights separately. That being the case, what cameras and what floodlights would you recommend? Not a fan of the privacy issues that have been exposed with Ring, Google, etc so would like to avoid those brands. Looking for quality resolution, reliability, and preferably nothing that requires any sort of cloud software.

Main dilemma:

I need coverage for front door, back door and am hoping to have coverage for my back surface lot as well, as there have been issues with tenants and neighbors' cars being broken into. The issue is, my backyard is pretty sizable and sits between the house and back surface lot (I'm just a girl so can't help with a numerical estimate on size of yard but have attached pics that hopefully offer some scale, what's visible in the picture is only about half of the yard). Ideally, I'd love to find a camera & floodlight that can adequately cover/capture the back of the house, yard + lot, but I doubt there's one on the market that could cover that amount of space, so I'm assuming I'd need a separate camera for the lot. The issue then becomes my Wi-Fi does not reach that far, so it would need to be a camera that can operate without Wi-Fi. If I'm not mistaken there are hardwired options that can operate without Wi-Fi, but with the lot so far from the house, the issue then becomes what would it get wired to?

First house, first time navigating surveillance system installs, please explain in "home security for dummies" terms :) Deeply appreciated!
