RE: Umbilical cord question
Waiting to cut the cord seemed like a good idea to me, but I never really researched it nor asked for it with either of my births. There were things that mattered a lot to me during and after labor, and those are the things I put in my birthplan, discussed with my husband and midwife, and focussed my internal attention on. Those birthplan worksheets can be detailed to the point of rigidity, so I would suggest you ask questions about all the options, as you are doing, but only make certain issues your priority.
Also, my second daughter had ABO incompatibility, a very treatable problem that sometimes happens if mom and baby are different blood types. I believe in that situation, late blood clamping isn't a great idea, but I don't think you know if your child has ABO incompatibility until after they have born. (Many people confuse it with Rh incompatibility, which is more serious and does involve some preemptive measures.) I bring this up because ABO incompatibility is a rather common problem, yet wasn't addressed in most of the late clamping info. I'd seen. It's something to ask your doctor about and factor into your research.
