I have a fairly low power Thinkpad laptop I got from edu ewaste that's currently running Debian that I think #NetBSD would be a good fit for except it has one of those ath10k wifi ac+Bluetooth which isn't really supported. I booted into nomad (freeBSD live distro) and everything else was ok..(no wifi there either, didn't check audio). Maybe I have a spare wifi card.....
It's funny, NetBSD runs on basically everything except mass produced consumer PCs 😂

Runs great on my T420, SparcLX, compaq P3, PMAX RISC, and VAX tho
The Trixie install is fairly lean and decently performant...
I think going forward though, Chimera will be my "lightweight" distro of choice default for more modern machines
