My recent birth was a UC, although unplanned. My first birth was extremely precipitous, though, so I had joked from the beginning about doing the "baby juggle" and had mentally prepared for the possibility that I might be birthing without my midwife or doula present. (Another extremely precipitous birth and my husband happened to be home, and we had already agreed that he wouldn't leave until the midwife arrived - he did not want to be present for the birth itself, and I supported that).
I honestly didn't plan anything ahead of time. My first baby was OP and I was so focused on THE WATER WILL HELP! and THIS IS HOW LABOR GOES! that what ended up happening took my understanding of labor and birth and completely flipped it. First babies aren't usually OP with active labor in the range of 20 minutes.
I hit a point where intuition took over and I did what felt right, and I let other people worry about the details.
This recent birth was between 60-90 minutes of active labor (as in, water literally popped and I went from lounging in bed and being lazy to OKAY I GUESS BABY IS COMING TODAY). I was focused initially on calling my midwife and doula, calling my mom (she wasn't going to be present for the birth, but I told her I'd call when I was in labor, and she could help distract me), and having my husband do some of the prep work (making Labor Aid, brewing hot water and herbs for various medicinal teas, etc). I didn't realize that this labor would be quick, and it took me by surprise when instinct kicked in and I told my husband to fill the tub while I sorted through my birth kit and tossed things in a laundry basket that I thought I might need in the bathtub. I still don't think I expected labor to go as quickly as it did until I had literally the same thoughts as I'd had with my first birth (and during my first, my midwife checked me during those thoughts and said I could get out and push if I wanted because yay transition).
Basically, mine was a lot of instinct. Having my husband be my "go-fer" was amazingly helpful because I could have him do whatever needed to be done (lots of Labor Aid refills - I get very hot and shaky in labor, apparently, and that helped) and I could just focus on labor and birth. I also ended up birthing on my hands and knees, and pushed when I felt ready - I was so focused that I couldn't catch my baby, or feel his head or watch him crown with a hand mirror, which is something that I had really wanted to do. My husband caught the baby and gave some loose direction (mild shoulder dystocia) which helped because I literally couldn't feel anything but pain and pressure until baby was born.
I don't know if any of that helps. I would just say go with instinct, and bonus points if you have someone there to mind all of the details. You COULD draw up a birth plan in case of transfer (one less thing to deal with should you transfer for whatever reason, even if you UC but have to go to a facility for postpartum or neonatal care) or a "labor list" for whoever might be present during your birth, things to prepare, people to call, etc. Handing my husband a paper I'd prepared was extremely helpful for both of us.
