OP here. Roughly 50GB in db size. Fairly standard queries (full-text search + filters). Most queries are on the order of 10-100ms. Some more complex ones involving business logic exceeds 100ms.

This is well within my budget, but it sounds like there might be room for improvements?

Regardless of your use case, EXPLAIN ANALYZE can show you whether there's any room for improvement.
