Apache AGE seems like a good way to have the battle testedness of Postgres with a more fluent query language. I have only used AGE in smaller projects so far however.
AGE actually looks very interesting. When I evaluated it a while back it seemed like the project wasn't very active and I couldn't find any information about folks using it at scale in production. If I was forced to use a graph database again, and I didn't immediately quit upon receiving that news, I might give AGE a look.
But only just. It doesn't really replace graph databases. It's mostly a slightly more convenient ways to write certain kinds of queries, but it doesn't come with anything else you might expect from a graph database.
