Less is more

I’m on a newbie routine (1 day on 1 day off).

Is it better to completely rest your unit on the resting days?

Or is it better to maintain a semi-erection throughout the resting days?

I don’t know how you would plan on maintaining a semi all day long. But blood flow is a good thing, it will help you heal. Although with a one day on one day off schedule your gains may be very slow in coming.

Try edging on rest days to keep blood flow going.

Have you written down your goal size? That’s the most essential thing I believe to get gains quickly. Activate the law of correspondence!
