If your Wifi gear supports it, you can hide the SSID to make it harder

Its trivial enough to find hidden SSIDs, that this is not worth doing
IMHO. Anyone capable of sticking up a fake wifi to masquerade as an
existing network, will also be able to see SSIDs hidden or not.

Yup.

If ya configure a laptop/mobile phone to connect to a hidden SSID, part
of the initial conversation from the device is "hello, SSID are you
there?". There isn't much encryption at this step, and if ye take ya
device walkabout with the WiFi switched on - it's gonna be having this
conversation with absolutely everything.

One day, something nefarious will answer - "yes, I'm SSID - I'm here,
give me any password. We can connect."
