A present when you do not know what they own
You know they photograph. You cannot ask without giving the present away.
You know they photograph. You do not know what is in the bag, and asking would give the whole thing away.
So give something that fits every camera ever made. Nothing below depends on the maker, none of it can be the wrong size, and none of it is a thing anybody minds having two of.
So the answer is
Peak Design Cuff wrist strap
A wrist strap for a small camera. Keeps it safe without a strap round their neck all day.

Two other ways to go
Another way
Altura Photo cleaning kit
A blower, a brush, and cloths. Dust on the front of a lens is the commonest reason a photograph looks soft, and it takes ten seconds to fix.
Another way
Manfrotto PIXI mini tripod
Small enough to live in a bag. Stands the camera on a table for a group photograph, and doubles as a grip for filming.
