>but why are half of yours combining 15A and 20A breakers
Because they're 15A and 20A circuits. They match the breaker to the wire.
>so they could cheap out with half 14AWG hots
This. They also didn't run a bunch of ground wires they said they ran. They just stuck 3 prongs in where my grandmother said she wanted grounded outlets and lied. Not everywhere, but in enough of the house that it's a bitch. Conversely we found a bedroom that as it turns out was grounded and was stuck with 2 prongs because nobody knew.
>how did they end up with lights downstream of GFCI outlets
Literally everything is downstream of outlets except the 7 240V circuits, the lights over the sink in the family room, the furnace/thermostat, the combination light/heater/fan for one of the bathrooms (sorta, it has a built in outlet in the housing), and IIRC some if not all of the basement lights. We're trying to upgrade the house to have GFCI everywhere appropriate or where needed due to the lack of grounds and it just worked out that they had to go in a lot of shitty positions to hit everything.
>And maybe they don't make them for that panel, but two-pole GFCI breakers are definitely a thing
You cannot put MWBCs on a GFCI. Any GFCI has to be after the split.
Also several of the breakers were incorrectly sized before, they had 2 15As on 20AWG lines, 2 20As on 14AWG lines, and a 30A on an 14AWG line. Oh, and I found every fuck up you can imagine working on the electrical before we got to the box up to and including just an uncapped live wire lying on top of metal ceiling light housing.

Edit: I misspoke, there are 8 MWBCs, not 9. Wasn't looking closely and thought the 240V on the right was a MWBC.
