Which is better for a home firewall or router build?

The Supermicro, because its four onboard Gigabit LAN ports remove the need for a network card. The ASRock has one Gigabit port, so you would add a card in its PCIe x16 slot.

Which is better for a general-purpose server?

The ASRock Rack X570D4U. A Ryzen 5000 CPU gives you more cores than the fixed 4-core EPYC 3101, and four DIMM slots allow more memory.

Is the Supermicro worth $178 more?

Only if you need four LAN ports and a soldered low-power EPYC. Otherwise the ASRock at $319 at DirectDial leaves budget for a CPU and memory.

Does the ASRock include a CPU?

No. It is a socket AM4 board, so you must buy a Ryzen 5000 series processor separately. The Supermicro's EPYC 3101 is already on the board.

Which supports ECC memory?

Both do. The Supermicro takes registered ECC DDR4 at 2666 MHz; the ASRock supports ECC DDR4 at up to 3200 MHz across four DIMM slots.

Which is easier to fit in a small case?

The Supermicro. Its Mini-ITX 6.7 x 6.7 in footprint fits small cases, while the ASRock is Micro ATX and needs a larger enclosure.
