There are a few, many of which are in common with simply hiking at night, but some are specific to geocaching. Firstly, the old scouts saying of be prepared! Make sure your torches, whether hand held or head, are properly charged (or you have spare batteries for them) as you don't want to get caught out in the dark without a light source. This also goes for ...
A hook/eyelet toggle bolt could work, depending on the weight of the cache: If you unscrew the toggles and reverse them, the hook would be on the inside holding the string, and you would reach in with two fingers and squeeze the toggles to extract the cache. Much cheaper than a climbing cam, but the same idea!
What's the width of the hole? I'm thinking of a mounting system like a wall socket. Spread it aginst the inner surface. Then tie the cach on it. Or the very low cost variant: Just use a piece of wire and bend it accordingly
I think what I would use would be a Rubber Washer: If you got a ~45mm rubber washer, you could tie your string to the washer, then put it into the hole one of two ways: either shove the washer in as deep as you can just to hold the string in place, or you could put your cache in first, then "plug" the hole with the washer. You could recess it completely ...
I bought a 1 lb bag of random foreign coins on eBay for $5. A cheap, neat little thing to find in a cache.
It already has a hole in it, what if you used a cam? Not exactly the cheapest method but potentially the easiest. Edit: if you found the perfect size Tricam that might be a less expensive option
A derivate of Geocashing is Geohashing, which started with an xkcd comic. The basic principle is the same: you take a pair of coordinates and try to get there. What differs is the way these coordinates are generated. As the page linked above describes, they are generated randomly each day for each 1°×1° latitude/longitude zone. A good place to look today's ...
Some other ideas: plasters/band-aid (if you don't worry about them getting "expired") cat-eye reflectors (even upcycled ones), to be mounted on bagpacks small, one-usage raincoats
