I'm not sure how much help I can be of, cause I've always pretty much known that I wanted meta for bottom surgery since early on in my transition, but then I have struggled between the options of meta or not doing anything at all or what exactly to do if meta. My dysphoria has been fluctuating too, over the years, and my coping mechanisms were sometimes helpful sometimes useless, which made an impact on how important I thought me having bottom surgery actually would be.
I know it can definitely be overwhelming, but know that you don't have to decide right away or even years from now. Give yourself time to take breaks from trying to decide as well, and time to process the different options available. And also maybe try to think of what would be most important functions for you rather than which surgical procedures, if that makes sense. Like for example instead of thinking if you'd want UL, ask yourself if it's important for you to be able to stand to pee and if so how important.
While sex is important for me, it's not in terms of penis size because I've never been into the idea of penetrating someone else. I prefer being on the receiving end of that, but not piv. Over all sensation and ability to orgasm are then of higher priority for me while I don't mind having a small penis as long as my external parts look male. And I really get dysphoric about my front hole mostly cause I get very excessive lubrication and there's no way I can stop its constant flow, so I do opt for a v-ectomy for that and other reasons. And hysto is of lower priority for me but is pretty much necessary when going for v-ectomy so I mostly go with it for that reason. I don't want kids either way. So for me making bottom surgery decisions with my sexuality in mind, would be very different compared to someone who does like penetrating a partner or to receive piv, for example. That's also an important note.
For me, figuring out what I wanted for bottom surgery was not like I just knew everything at once. Some things took longer for me to decide over while others were easier for me to know more quickly. Some procedures are more pressingly important to me/of high priority, while others are more like "I think I'd regret it if I opt out of this one" but of lower priority. I think what helped me starting to get to a final decision was trying to see the full picture instead of just procedure by procedure and thinking about how it could realistically affect my every day life when post-op and healed up.
I might be lucky to have a very vivid imagination, but if you're also quite good at creating mental images of a possible future, I think that might be a good thing to do too cause it has helped me trying to figure out how I could likely feel about actually having either procedure I was considering as well as what I wasn't considering just to compare. For me it was almost like I had to back-track myself and stop myself to ask why I was always so sure I didn't want phallo just to be sure I had my reasons in order and knew what I was rejecting vs. what I was getting myself into.
