My cameras are all wifi-based and most have cloud storage so no recommendations based on your requirements.

I'd lean towards PoE for your system. I'm not an expert but I expect it simplifies the set up and maintenance. You'll probably need additional lighting if you want decent nighttime captures. Make sure the system has person detection. I mostly get moths, foxes, raccoons and skunks on my cameras at night. Hedges and trees set off some of the cameras when it's windy.

One thing to check is whether you can monitor your cameras in a web browser and on Echo or Google video devices, if you have those.
