SlabSlayer did a great job answering your questions. I can add a couple more points to consider. Wyze has a new Battery Cam Pro which is 2.4Ghz and 5Ghz. Otherwise, the rest of the Wyze cameras are only 2.4Ghz. My v3 cameras are almost 2years old and working great so I am sticking with Wyze wired v3 cameras.
You might consider mounting your v3 cameras inside looking out. Here is a thread with picture examples of the results you can expect. I do this because I have electrical outlets near each window, my cameras are not in the weather and no mounting outside concerns.
It sounds like you will be using Wyze to supplement Blink cameras. Be sure to read through the threads on camera firmware and App upgrades as sometimes bugs can appear. Determine how quickly you want to jump on new camera firmware and new App versions. I only have Wyze v3 cameras (no other brands), so I wait until I read positive forum comments on mission critical cameras before updating firmware. I will update firmware early on cameras in less important areas to test the newer software.
If you are interested in Cam Plus Lite where you can choose to pay any amount including Zero, be sure to check this list of compatible cameras (as the newest Wyze cameras will not work on Lite). Wyze regular v3 cameras will work on Lite.
