I'm leaning towards using a metal clamp of some type. If you run electrical tape underneath, it won't scratch the paint.
Alternatively I like some the bikepacking bags that hold a nalgene bottle and mount under the downtube but they're expensive.
As for electrical tape, you could also get Tessa tape. It's made of fabric and looks pretty nice on vintage frames.
One of my first bicycles had two clamps holding a bottle cage. There seem to be many solutions these days:
