every time somebody posts the M5stack site, i just want to order everything.

but on some level, i know it'll all end up on the pile of projects that i've started and not yet finished.

Yes, though note you'd need to add a few modules to get the full capabilities of the FZ (eg the RFID reading and 432Hz antennas iirc). Be warned that the documentation is kinda minimal, so if you're new to IOT stuff there's quite a learning curve. There are fairly decent core libraries in C and also a fairly capable micropython stock, but you have to be willing to figure out a lot of stuff on your own or with the help of their user forums.
