Somewhat combining the two topics, yeah the whole... stuff from the opening issue was a huge huge issue for me. It absolutely did make intimacy very very difficult (even though it didn't bother my wife).
Honestly, if you can get it all done as a part of your hysto, I would say absolutely go for it. The only potential drawback I see is if your future phalloplasty surgeon wanted to use some of that tissue. So I think checking on a few of your preferred surgeons and how they usually do their surgeries first would help you know what the best option is.
I will say no longer having the hole is a huuuuuuuuugggggggeeeeee step forward for me. I love intimacy with my wife now. The combination of the metoidioplasty and the colpectomy was life changing for my sex life.
Glad I've been helpful. Certainly feel free to ask me anything else you are curious about!
