You had me thinking Bobby , my wife has a new Lariat $$ . I was thinking another new one .... WOW !
I use 10awg for my mobile installs and here at the house as well. Figure 30 amps will go thru 10 at your house just fine.. 12awg is rated for like 20amps.. 8awg is 50 amps..
Hope that helps..
10 is still flexible enough in even cheap THHN. Just be sure to grommet the pass thru holes.. marine grade is nice as it's flexible but costs a tiny bit more.. again grommet the holes..

Just did the sons SUV with a 10-AWG single-wire from BATT (BUSSMANN termination fuse) back to firewall and across to passenger side to an existing hole.
Into interior and he ran it under center console to rear. NEG at seatbolt. Maybe 15’ or so TTL circuit length from SOTABEAM APP-equipped 12V distribution box.
Using the MARINCO 3% Voltage Drop Calculator showed that was at the edge for a 20A draw so the (McK + KL-203) squeaked in under the bar.
Test showed 14.1V (on; no PTT) at engine resting idle. We did install fast as possible as no time to lose thus minimal testing.
10-AWG is hard to argue with.
