Would belly bands/diapers be helpful or harmful while house training?

In January, I will be bringing home my second dog, an 8 week old male Doberman puppy. I had no trouble house training my first pup through a combination of crating, tethering, and careful supervision to try to eliminate all accidents and interrupt those that do happen. However, I am now living in a second floor apartment with no yard, it will be the middle of winter, I will have a full-time job (I will WFH for a couple of weeks but still). Basically, I expect interrupting accidents and getting my dog outside in time to be way harder this time around.

I’m curious if anyone has experience using belly bands or diapers to prevent damage from accidents while house training. Would a belly band be enough to hold in a puppy accident while I rush my dog down the nearest staircase? Will it teach bad behavior like peeing inside because there’s a layer of protection in place? I am not expecting the belly band or diapers to take the place of house training, just want to know if it could help limit the damage due to accidents while I’m working on it.

I do not want to use pee pads as I believe teaching a dog to pee inside in a single place is confusing and leads to less solid house training long term. If my dog always had accidents in one area (ex. by the front door) I could place down a pee pad there, but I’m trying to find a more consistent way to prevent messes.
