CAT6 or CAT6A STP would be recommended run out to the garage.

I work out of my garage and don't get any wifi signal. I do have an Ethernet cable running from my home to the garage. If I buy a good mesh system, could I connect one of the satellite nodes to another using the Ethernet cable and have that whole setup on the same wifi/ssid?

Assuming that the Ethernet cable to the garage is less than 300 ft., then Yes.  Most of the modern mesh WiFi systems will create a seamless network including the house and garage.  Netgear Orbi systems can be connected with Ethernet, as can eero.  As for Asus,  Linksys, TP-Link, etc., you would have to check their documentation.
