Well, it's pretty much the usual suspects. If cable gets warm it's too small or has a bad connection. If smoke at the solenoid then obviously that's not right either. Probably should try a new solenoid.

Sounds like starter to me. I've opened starters up and cleaned all the debris out...more of an experiment than a repair. In my experience that perks them right back up but it is certainly not a long term fix.

Yiu would be best to clean the terminals where the smoking started. The smoking is also an indication that you have corroded connections or solder bloom which insulates the terminals and causing them to heat up when you pass a lot of amperage thru them.

Also, for DG try this.

Will save you a trip to repair shop.;)

I would start cleaning all connection involved, grounds, hot wires, switch terminals, etc, before I went to expense of anything at all, or replacing anything, and I have spare parts laying around to use

If you hotwire power down to the starter does it crank nice or still slow. If it is still slow it is the starter. If it is fast it's somewhere in the middle.
