My SO unfortunately has 2 ipones, an ipad and a MBP. There is a confluence of DHCP activity from all these devices that is guaranteed to take my network down.

DHCP activity from 4 devices will not slow your network, much less take it down. A DHCP negotiation to get an IP address takes 4 UDP packets, all of them usually below 500 bytes in size. Not even when you have set the lease time to the theoretical minimum of 1s, this traffic will be at all significant in your network.

  It will kill my fiber to the home network box that my telco installed, and provides DHCP. It isn't a load issue, it is a "the DHCP server died" issue

    "It" won't. Bugs in DHCP / your router/modem/telco's software will.

    I would be talking to my telco in this instance.

Our home network has 6+ Apple devices and a pile of other stuff (Smart TVs, DVRs, game consoles, media converters, etc) and it has zero problems whatsoever. Our router is some generic thing by NEC that I bought off the shelf at a big-box retailer because it had the biggest numbers on the box.

Unless your DHCP server is an old Commodore 64, that's not the right diagnosis. The ISC DHCP server was rock solid with negligible CPU load with many thousands of clients even 10-15 years ago. If your network is really having problems, either dig deeper if you want to learn more about networking or buy something like a Google WiFi device if you just want something known to handle much greater loads without issue.

    That's a bug in that software stack which is unique to however they've designed it. The right thing to do is fix it or replace it rather than blaming the vendor you notice problems with, just as you wouldn't blame a pothole on the first car to hit it.
