If it's a small child, a plushie and children's book from my little hodler.

If it's an orange pill mission or new person otherwise a hard copy of a book or books from the saif house.

If it's someone with laser eyes but using one of the less stellar signing devices (ledger, trezor, etc), a coldcard.

And if it's someone who's got all that but no node, some hardware and a date to help them get a node up and running.

If they have all that maybe some swag, or if appropriate, zap some sats. Also, Salvadoran bitcoin friendly coffee doesn't hurt.
