Is there a bus protocol similar to CAN bus except with ethernet sized frames?

Not point to point like SLIP, but a multi-device bus.

In the olden days there was 10base2 over coax but that disappeared long ago. Is there a modern equivalent?

Well, there is CAN FD, which can have 64 bytes of payload data per message, but that is only equivalent to the least amount of data an ethernet frame can carry.

RS-485 with your own protocol / packetisation?

There's nothing stopping you from using CAN (or RS-485) physical layer components and writing your own ethernet-like protocol. Whether the amount of work required is justified here I leave to you to decide.

Flexray is somewhere in the middle. 254 byte payload, looks to be time triggered instead of CSMA, ~10Mbps.
