Lots of surprisingly useful practical info there, for a Veritasium video*:

• sand surfaces to make superglue stick better
• water triggers gluing (more specifically, the polymerisation that glues things together)
• acetone is your best bet to remove super glue

I also checked ethyl acetate; local nail polishers are based on that, since acetone has controlled sales (in most Brazilian states you can buy it but there’s some bureaucracy involved). Ethyl acetate seems to be okay to remove it, but inferior to acetone.

*I’m not saying his vids are bad, far from that - they’re good. However they’re mostly focused on theoretical explanation, not practical stuff.
