I use Trello as well. It actually helped quite a bit launching my current endeavor, as I picked what as the MVP at the beginning. I had a "For Launch" column in addition to the ones you mentioned. It kept me focused when my brain would've had me work on other things.

I'm doing the same thing but with Asana just because it's what I use daily anyway, using their sections as the types. It's not great but like you said, laying it out in the beginning keeps the scope contained and I can list off bugs I find.

Sounds like a good idea.

The new github projects feature looks like something that would work well for this purpose, as you can mix it with milestones as well as a kanban board (Trello). GitLab also has this feature and is open-source.
