From what I've seen, jq -s add *.json merges objects only at the top level (i.e. not recursively), and jq -s '.' *.json creates an array with each element being one of the JSON files.
The command Ouss wrote just hung for me, so I don't know about that.
I ended up using the following, which simple enough and worked for me to perform a recursive merge of multiple JSON files:
jq -s 'reduce .[] as $obj ({}; . * $obj)' *.json
