Where is all my ESPHome sensor data stored and is that something I need to consider?

I am still trying to get my bearings with ESPHome and as I add circuit-level energy monitoring to my system in addition to future sensors I started to wonder where all of this gets stored.

I have MariaDB & InfluxDB running on my general install, but I can’t explicitly remember whether ESPHome links to either by default.

Among other things, I would like to avoid some inefficient and huge database that I should have setup differently.

Is this an issue?

The ESPHome devices connect directly to HA and exposes all the sensors there.

So the sensor data is stored in your usual HA db whether its the built-in db or if you have Mariadb setup or whatever you use.
