I am familiar with using solid state relays to switch 110VAC using a low
DC voltage to activate. Can these also be used to switch 12VDC (to pick
a 12 volt mechanical relay)?

Assuming you mean **to replace**, sure.
Select such that the on state resistance won't affect the results.

On the 2nd page under "Relays"
"Solid State(3854 items)",
enter some parameters and see what's available.

A solid state relay that is designed for AC won't work to switch DC
and Vice Versa
