You're overthinking it. Even a cheap vinyl will last a few days and remove without issue. I've hand cut some out of no-name black vinyl from Michael's (craft supplies and hobby shop). Just don't leave them on there baking in the sun for months.
You're going to have bigger paint issues on track, and those issues don't come from stuff that you put on your car
Even when they do get baked on, it might leave a residue imprint if you have a light colored car. I would gander that can be fixed with a DA machine and some compound+polish. The worst part of removing baked on stickers is scraping and flaking all of the brittle vinyl material off, then being patient with goo-gone with any of the adhesive that didn't come up with the vinyl. Again baking on doesn't happen in days, even weeks. It takes months and years.
