After two years of sliding my boots around on bare painted floor panels every time I got in and out of the car, I finally sorted it with grip tape. Learned a few things the hard way so figured I'd pass them on. Clean the metal properly first. I wiped mine down with isopropyl alcohol and let it flash off before touching anything. Skipping that is why my first attempt peeled at the edges within a month. Second tip: cut your shapes before peeling any backing. I traced the outlines on the paper side with a Sharpie, then cut with a fresh blade on a cutting mat. Skateboard grip tape is abrasive enough to chew up a dull blade fast, so swap blades halfway through if you're doing lots of small pieces. The trick nobody tells you is working from one edge and rolling it down as you go. If you lay the whole piece flat and press from the middle, you trap air pockets and it never sits right. Once it's down, go over it firmly with a rag-wrapped block. I cut mine into heel-shaped pads and a couple of arrow markers so folks know where to step when climbing in. Looks sharp and my shoes finally stay put.
Tips for grip tape on floor pans that nobody talks about

I did the same thing on my truck's running boards last fall and your point about cutting before peeling is spot on. I tried to trim one piece in place and the blade wandered all over the place on that grit surface. Wound up with a crooked edge that bugged me every time I looked at it untill I ripped it off and redid it.
One thing that helped me was warming the tape with a hair dryer before pressing it down, especally since I did the job in my garage in October when it was pretty cold out. The adhesive grabbed way better warm. Also, leave a small gap between pieces instead of butting them tight. The tape swells just a hair when it gets wet and butted edges will curl up on you. I used the black perforated style instead of solid because my boards get rained on and I figured water needed somewhere to go. Drilled a couple of extra drain holes in the boards too while I had the tape out. A year later everything is still stuck down flat except one corner where I got lazy with the alcohol wipe, wich lines up exactly with what you said about surface prep. That stuff really is unforgiving.
Back in the day on the old hot rods we never had fancy tape, we'd sprinkle grit onto wet paint before it cured. Worked fine but you had to repaint every few years when it wore smooth. The tape stuff now is a whole lot easier to live with. One thing I'd add, when it finally wears out or you want to change it, warm it with a heat gun and pull slow at a low angle. Comes off clean that way instead of leaving shredded black bits all over the paint.
Not buying the swelling explanation honestly. I butted my pieces tight on the passenger side of my wagon two summers back and they get soaked every winter with wet boots and slush, never curled once. When edges lift it's almost always because the surface wasn't clean enough under that spot, not the tape expanding. My driver side had one corner lift and I know for a fact I skimped on the prep there. That said, a tiny gap does hide sloppy cuts better, so I get why it looks nicer. But calling it swelling feels like blaming the tape for what the alcohol wipe would've fixed.
