Hi Samuel, Welcome. I highly recommend this online course:
http://leeming-consulting.com/SchoolNet/courses/beekeeping1.0/index.htmlAlthough you may know some of the info, repetition ties new information to what you already know.
Most people learn best by "grouping" information this way. That's why "memory palace" techniques work so well.
Best of all, you can read this course on your phone. There are quizzes to check your memory on life cycles in the hive. That's one of the most important things you can learn, because when you inspect, you can use decision trees to see if everything's doing fine, or if something needs to be changed or helped.
I agree that if you can start with feral bees from a swarm trap or cut out, you are far, far ahead. They are survivors.
I'm of the opinion that bee colonies are stressed in large bee raising ops. They've been fed synthetic pollen and high fructose corn syrup. And if your bees were used for pollination, the bees dealt with insecticides, were bounced around highways breathing exhaust and propane forklift fumes...etc. Do you buy the sickest, mangiest chickens? No.
Start with bees that are local ferals, or from a hobbyist that respects bee health. Cheers!
