I like specifications of raspberry pi zero, and i want to make similar router-like device. The device is intended for some statistics monitoring, it should collect statistic from multiple hosts and aggregate it. Number of hosts is huge, and stability\latency is very important, so WiFI cannot be used. Device should have just simple web interface via Ethernet (like home routers usually do). But the board lacks ethernet port, and it have (unwanted/expensive) hdmi port. I dont need graphics at all.

What platforms, or boards are usually used for this product group? (What model usually used by developers while developing/debugging firmware for router-like or IoT-like devices?)

You still can use the Raspberry Pi Zero by using an USB to Ethernet adaptor. If you need the USB port for other purposes. You can use the pretty cheap ENC28J60 SPI to ethernet adaptor. The Raspberry Pi Kernel has the support for it built-in but it only offers 10 Mbit/s.

If you want to keep the footprint small, why not using Wi-Fi?

So it greatly depends on your need and willingness to leave the paths other have paved for your and wade in unknown waterst.

My recommendation is to stick with the Pi that suits your needs. Picking other boards may or may not be very frustrating to use.

If you really wanna have a small footprint with the least cost, invest any inexpensive OTG Male USB2 to Male Micro USB2 adapter ([1], [2], [3], etc.) to connect the USB port on your Rpi0 to any USB2 ports on your network device and configure the network device as a network bridge + your Rpi0 as a USB Ethernet gadget. Whatever you do, please don't get this Top Quality OTG Cable Mini USB 2.0 Micro USB OTG Converter Adapter. Despites claimed by the ad, it is NOT an OTG adapter! I had bought this USB Mini 5Pin Female to Micro 5Pin Male 90 Degree Angle Adapter to bridge my Rpi0 to a Seagate Dockstar as shown in a picture attached to my post which also shows how to configure an Rpi0 as a USB Ethernet gadget. As you can see from my post, I run into a reboot issue. I don't know if it is a localized issue or not, but feel free to give it a try.

As of Oct. 2018 all available variations of the models of the Raspberry Pi (Model A 1, 1+; Model B 1, 1+, 2, 3, 3+; Zero; Zero W) come with GPU and HDMI video output as well as HDMI connectors soldered to the boards. The only Raspberry boards that do not have any HDMI connectors attached are the Compute Modules (1, 3, and 3lite). These however also lack on-board ethernet connectivity.

Bottom line: there is no Raspberry Pi to fulfill this specification - yet, though I somewhat doubt we will ever see a Pi w/o video out given the mission of the Raspberry Pi Foundation and how the respective targeted use cases will dictate certain design decisions.
