Sounds like you did very well. No major mistakes that I could detect, but I have a few suggestions.
I don’t usually destroy queen cells or play cups - they just make more when I am not looking! If they intend to swarm, destroying the cells doesn’t prevent them from doing so.
Personally I usually only rotate 2 frames out of the brood box at once, but then I have 8 frame brood boxes not 10 frames. If the hive was very crowded, you have not hurt them by removing 3 frames, but it will generate a lot of work for them to draw out the comb, which will slow them down a bit. That may be fine if the nectar flow is strong, and will certainly help deter them from swarming if they felt short of space.
One other thing to consider. If there was drone brood in the frames you put above the queen excluder, you will need to give them an upper entrance until they have all emerged. Drones cannot get through the queen excluder, and will kill themselves trying to do so unless you let them out.
When I am tidying up that kind of comb, I take a large ziplock bag with me and put the comb into it. I can then crush and strain it, or just put it into an old kitchen sieve and let the honey drip out. I freeze the wax to kill off wax moth and hive beetle eggs, then render it when I have collected enough for it to be worthwhile.
