I was really hoping that FreeBSD would support Apple Silicon, particularly the Mini. Hector Martin and friends did the hard and under appreciated work of the m1n1 bootstrap. Indeed, OpenBSD uses m1n1. However, the FreeBSD effort seems to have stalled.

FreeBSD has had a hard time supporting Intel Thinkpads, and they're making progress at getting better. Supporting Apple arm64 is a much heavier lift than that.
