It probably makes sense for a single speaker cab. If the amp is 8/16 you can go series. I have an amp like that. How often would it come into play with 2 or 4 speaker cabs?

Is that standard on amps? They don't ever wire dual outputs in series?

Ahhhh....good point. And the whole amp as well, eh? Makes sense.If you wired them in series and blew a speaker on the first out you'd lose the second out.
NO! Cab's are typically connected in parallel when you daisy-chain several cab's. Plugging into 2 4-ohm cab's would show your amp a load of 2 ohms. That will be very bad for you amp, it's suck waaay to much current and probably fry your amp.
What you need to do is get those 2 4-ohm cab's wired up in SERIES. 2 4-ohm cab's in series would be 8 ohms.
OR probably easier - re-wire the speakers in each cab so each cab is 16 ohms instead. A 4-ohm 8x10 is probably all 8-ohm speakers wired as 4 sets of (2 speakers in parallel to 4 ohms). Those 4 2-speaker sets are wired series/parallel to grand total 4-ohm load. What you need to do is wire those 4 2-speaker sets in series to produce a 16-ohm cab. THEN you can daisy chain the 2 cabs in parallel to achieve the 8-ohm load load your amp wants.
What's the safest way to connect them to a head (to simplify, how many ohms does my head need to be to safely run two 8x10s in PARALLEL? SERIES? TWO OUTPUTS, TWO CABS. One output, two cabs.
Well, if you had four of them, you could make an 8 ohm load by wiring two sets of two speakers in series and plugging the sets into the two amp outputs (parallel)It probably makes sense for a single speaker cab.
