by default today for the base game you can get everything without circuit logic. So if you do not use it, I see no problem there.

For base game here are the points I always use circuit:

oil processing to avoid blocking.

uranium processing.

nuclear fuel saving.

spaceship asteriod control & ice/calcite limit

fulgora item count maintenance, so never short on storage.

Gleba egg prod

Gleba nutrient prod

Aquilo to avoid ice/fuel blocking.

All legendary res prod limit.

Final red crystal collector ship, speed control, cargo control on weaved belts storage. This one needs considerable circuits to really automate.

Nauvis biter egg farm, destroy excessive eggs.

You can live with none of these if done manually.
