What exact welding machine would you recommend for someone that has never done it before but wants to build a significant structures (a greenhouse, bunk bed, work table etc.)? What YouTube channel or books/other resources do you recommend?

I would suggest finding a community college or hardware hacker space like The Crucible in Oakland, CA to take a class. Nothing like hands-on instruction and having the machines set up perfectly so you can concentrate on your skills and get immediate feedback.

A MIG welder is probably easiest to learn. I haven't watched YouTube videos but see there are many. Learn to Weld by Christena is a popular beginners book. Have fun!
