Hi Maria good seeing ya and hope all is going well
Good to hear you managed to find some kind of useful amongst my ramblings.
Having never attempting to run photos full term in a 1L i can't really offer more than speculation and food for thought. I would think they would continue to get bigger the longer you veg them till they fill the pot with roots and start to tap out and get sick once what is in the pot is not enough to supply them, so with that would say as short as possible veg would be best to keep the plant at a size that can kept healthy, remember though this is just speculation and might want to tag in some photo gurus to give a more solid opinion than i can offer.
As for topping i am wary of it with autos in small pots after the funky stunting that happened on my Alien X SODK, as the veg time with autos seems to shortened even more in a smaller pot it doesn't quite seem to give them enough time to bounce back from anything to brutal. With photos they should be more forgiving and could chop, crop and top them into shape before flipping over to 12/12 and have them bounce back before flower with a good sized/shaped plant for the pot.
As for yield with autos always seems to be between 10g-15g per plant for me in the past, but reckon an oz could be easily possible with the right strain and a green thumb, just as 1g-5g could also with to much of a feck up.
Peace mate and will check out the journal a bit later when i get a spare moment
