50 gallon stocking

Personally, I might skip the swords and go with 8 or so hatchets and 8-10 of one sort of tetra (along with your otos and corys-maybe even a few more of them)and call it a day. Fish usually school better when there are more and IMO that looks cooler than a mish mash of different fish. I consolidated 2 smaller tanks into a large one and now I have a mish mash... wish it was just more of a couple of the fish I have. I could be wrong, but I think all the smaller fish might be too much action for the angels. Maybe the dwarf gourami...

4 otos - Wait a while on these. Until you have algae actively growing, they are likely to starve.
5 cory catfish - Good plan.
3 swordtails - Meh. I would skip them. They tend to be "pushy" with smaller fish.
4 hatchets - Good plan. I would get more, though. Maybe 6.
1 or 2 schools of 6 of a type of tetra - Good plan. Your options are wide open here, except maybe cardinals and small rummy-noses (possibly angel snacks). Bleeding hearts, black skirts, lemons, silvertips, neons, glowlights, diamonds (if you can find them), and many others would be fine choices.
I would add two angels and call it done. My angels are full-grown and don't chase, harrass or attempt to eat the glowlight and black neon tetras in their tank. Once you're cycled, I would start with the cories. A week later, tetras. Another week, then hatchets. I'd wait 2-3 weeks after that to add otos and angels.
