I was going through this process about a year ago. I ended up settling on the Protectli V1410 (Intel N5105 and 4 Intel I226-V 2.5Gbps ports) because: a) I wanted coreboot, b) I was a little wary of lesser-known Ali Express sellers c) Protectli seemed like a decent company and I felt good about supporting people investing in an open source firmware (minus proprietary blobs which you can’t do much about). None of that was strictly necessary, and you probably would be fine just going with a cheaper NUC or mini PC. I would definitely second some of the other comments on avoiding Realtek NICs though.
