This (the 16GB version) should not fit into most use cases. You’re buying an expensive RAM chip with a Pi attached.
The cheaper 4GB or even 1GB versions ($50 for the latter) are what most people should be looking at for their projects.
My personal fave RPi, the Zero W, is still $15 from Adafruit.
I have decided that the Pi4 1GB is the ideal for hobbyists. Faster than Pi3, takes normal USB-C charging, and can do most single server or electronics jobs. Which is why it is currently sold out.
