Our original 1990’s Honeywell Thermostat is circling the drain. Looking to replace with a new smart thermostat. Here is what it looks like with the cover off. Doable for a mid DIY guy like me or not?

Even if you don’t have a C wire, you can use an external power brick to power the smart thermostat in place of a C wire. Otherwise at least the Honeywell thermostats come with a C-wire adapter than can be wired into your furnace control box and shifts some of the wires around to provide a C wire. I found the external power brick to be a little less daunting, but either option should work for you.
