Remember, not all DCC systems support the Engine Zero option. My Lenz system does, but some do not.
It’s a weak choice. DC engines on my layout will only run at half speed or so, make a lot of noise, and auto reversers will not work.
My first DCC system was a MRC2K with five throttles. Throttle one could run a DCC or DC loco. Never had an issue with half speed.
I could run a freight with a DCC loco pulling and a DC loco pushing.
Yes, the DC loco buzzed. I would park it when not using it. The motor brushes get hotter where they contact the armature when the loco is stopped and DCC still on the rails.
The AC component vibrated the motor armature at the DCC frequency. I did temp measurements with an infra red temp scanner on a loco wheel rack.
Gave the system away and went full DCC.

Thanks everyone. It sounds like I need to put a lot of thought into this before charging ahead. I have a Digitrax system (beginners model). I am by no means great at wiring, so that will probably make my decision that much easier.

The reason you get answers like this is because new DCC users are the ones who ask. That is what happened at our club. One person was not paying attention to the control panel for block control. Gabbing.
Just be very careful that there will be no possible way for the loco, tender wheels to contact DC and DCC rails.
Post a diagram here of what you would like to do.
Someone with electrical experince can do it. Maybe a lone wolf. We could have but, talk, talk, talk.
