I don’t have any experience trapping, but I have “hand caught” three adult cats and one kitten. My only piece of advice is don’t underestimate the kittens. Mine (appropriately named Kitten because I did not intend to keep him, so I did not name him and I did not like the name the vets picked) was both the hardest to catch and the hardest to socialize. The primary reason I still have him is that he was utterly feral and took forever to socialize, even though he was tiny and estimated to be only 7-8 weeks when I plucked him (after over an hour in a torrential storm) from a neighbor’s car engine.
ETA: he is a love bug now, but still VERY flighty.
