I have been using FreeBSD as my primary OS since version 1.1.5, and I am currently running 12.4 on a Lenovo T480.

This is what works flawlessly on my configuration (SSD, 8G bytes of RAM): gigabit ethernet, second monitor via HDMI, USB mouse and keyboard, sound via audio jack, video playback on both the internal and external monitor. What I have not tried is Wifi, Bluetooth, the fingerprint reader, and the touchpad (disabled via BIOS). The trackpoint and buttons do work.

IMHO, FreeBSD is a nice system for everyday use. Note, though, that I do mostly terminal-based stuff (and some Ghostview, PDF reading, web browsing, occasional video watching, etc), so YMMV.
