4@12v = 24v
I'm installing 4 -12v AGM batteries to power a 24v inverter. This is my first choice for wiring: and my second: Any pros or cons to either one?

Higher voltage is done primarily to reduce wiring losses or allow the use of lighter gauge wire. Higher (input) voltage inverters also tend to be a little more efficient. And higher voltage battery banks usually have more batteries wired in series, which forces each of them to share an equal amount of current. Current sharing in parallel batteries can become imbalanced (especially as the bank ages), which leads to shorter battery bank life and reduced overall capacity.
