ethernet-ports are preferred.

This is backwards to me, instead of an 'ethernet-switch' with 'ports',
we have a 'switch' with 'ethernet-ports'. Whatever.

The rationale AFAIR was that dual Ethernet port controllers like TI's CPSW needed to describe each port as a pseudo Ethernet MAC and using 'ethernet-ports' as a contained allowed to disambiguate with the 'ports' container used in display subsystem descriptions. We should probably enforce or recommend 'ethernet-switch' to be used as the node name for Ethernet switch devices though.
