Are you drawn more towards animals? Plants?
For primarily veg focused farming, some great resources:
Farmer to Farmer podcast —> this covers a huge diversity of business models and scales within vegetable farming, also gets into life stories and evolution of farms rather than just nuts and bolts production
Farm Small, Farm Smart podcast —> tends to focus mostly on salad green and other high profit (but high labor) crops

Diego Footer YouTube channel (Diego does the Farm Small podcast as well)
For animal farming, my favorite is the Grass Fed Life podcast.
For a fascinating diversified farmer in a very challenging climate (rural Sweden) who is very Mustachian in his approach to using as much salvaged materials, but also knowing when to invest heavily in expensive projects, etc. watch Richard Perkins on YouTube.
Lots of others. A lot really depends on your area, what niches there are in the market that are underserved in quantity, quality, or variety, and what you enjoy doing.
I really wouldn’t even think of doing it if you don’t enjoy the process. You have to really love it.
If you’re not already familiar with spreadsheets, learn to love them. Way too many farmers, especially at hobby/PT level, are terrible at spreadsheets and drastically undercharge for their product, and as a result are working for well below minimum wage.
I love talking stuff like this, though I personally am an urban homesteader without the time or land base to sell much currently. I track my animal expenses (chicken eggs and meat rabbits) to the penny as if I was a commercial farmer, but gardening I do just for fun now after trying a small remote market garden for a couple years that took too much time away from my homeschool duties.
