Nice project, that box is really satisfying to build.
Two major methods are common: duct tape and plastic razors.
Duct tape: About what you think, you stick duct tape to the whole area, then peel it off. if it goes well, the duct tape is stickier than the masking is, and the tape pulls all the masking up at once. Most people swear by Gorilla brand duct tape. It’s pretty great. I like the wider roll, it’s more efficient when pulling larger areas.

Plastic razors: You gently scrape your surface, it lifts tiny bits of masking up. It’s fast and effective.

Both methods have their places, I have both and use them in different situations. If you’re careful with the razors they’ll last for ages, I’ve gone through like 4 since I started and that’s only because I broke a few on 3d printing projects.
As for other tips and tricks, I’d recommend this post:
Particularly the accessories link. All kinds of gems in there.
