I haven't spent time optimizing TLS between a database client and server, but in HTTPS, using TLS 1.3 without early data (or TLS 1.2 with somewhat optimistic handshake handling) gets you to one added roundtrip, TLS 1.3 early data gets you down to zero added round trips. Early data isn't always appropriate, because there's potential for replays, but the latency improvement might be worth considering for some selects.
