Athletic tape is my all-purpose first-aid tape. Strong, strong adhesive, water resistant. Clean the skin with alcohol before application and you can use it as butterflies, hold IV tubing, ET tubes, assemble splints and bind sprains.

In mass casualty situations a six-pack of athletic tape goes pretty far. An alternative is a good contractor grade of duct tape or grip tape. You can do any taping with these general-purpose tapes.

I have used electrical tape but it was only because I had it close to hand. The black stick-um gets pretty messy.

If the person has an allergy I get old-school and don't use tape. Safety pins, triangle bandages and knowing how to tear gauze wraps so it has tails and tying it off makes a workable bandage with no risk of allergic reaction. A well tied bandage is often more resistant to movement and water than what you can do with any tape.

Superglue is good to have around. I like the liquid stuff that comes with a brush. Just don't spill it.
