You're not the only one. There are lots of better alternatives to SQL databases for most use cases (I'm lucky enough to have worked in some places where SQL datastores were the exception rather than the rule). But it takes a long time for cultural change to happen.

Would you mind mentioning some good options? I've always been interested in databases, but find it hard to know which ones to learn more about and when they'd actually be worth investing in (especially since it's hard to build knowledge from toy projects).

Honestly all the popular datastores are fine, though they all have their own foibles. Redis is fine if you just want a basic key-value store that's not HA (and not particularly durable). Cassandra is fine if you want HA (Riak had a better design, but is so much less popular that I probably wouldn't use it these days). Kafka is really good but a much bigger conceptual leap. Even MongoDB is pretty much fine - there are plenty of horror stories about data loss in earlier versions, but it pretty much works most of the time, which is the best you can ever really say about any datastore IME (even PostgreSQL).
