The Orange Pi Zero would be ARMv7. I still have 2 or 3 of those lying around from small projects and "just for playing around" because they once were dirt cheap at ~10-12$ from china. nowadays they seem to sell more at ~30$, so not that cheap anymore but still OK-ish compared to other boards. I've been running OpenBSD on them, but IIRC FreeBSD should also work fine. NIC is only 100MBit though, but supports PoE (optional).
The Orange Pi Zero 2 comes with an Allwinner H616 (Cortex A53) and Gbit ethernet, but I havent' gotten my hands on one of those yet. There's also another variant with ARM Cortex A53 (Rockchip RK3328) available with dual gbit NICs which looks interesting.
