Help us decide: bridal party, just moh & Best Man, no bridal party

We have been planning our wedding since last summer, and it is quickly approaching in about 8 months. We're in our early/mid 30s. Originally, we weren't going to have a bridal party, not even a maid of honor or best man. Our vision was a romantic one, really to celebrate us as a couple with ALL the people who love and support us as guests! And we can't wait. But, we didn't firmly decide that, I guess. Since then, lots of people have asked if we're having a bridal party, my FMIL has asked multiple times what we've decided for our best man/maid of honor when she already knew we were thinking we wouldn't have any. The reason we didn't firmly decide that is, my fiance is going to be best man in his brother's wedding in summer, and I feel that he would probably like to return the favor. And I'm sure my FMIL would love to see that too. My FBIL's wedding is having my fiance as best man, and my FSIL is having her sister as MOH, no other bridal party. I want him to be happy with our decision and we've talked about it a lot, with not many conclusions other than not having any but not feeling 100% about it. He says he'd be happy either way, having his brother be Best Man or simply having his brother give a toast at our reception. If he has him be best man, I run into an issue of having to pick a MOH. I have 2 best friends, one who is married and amped about us getting married and one who is in a relationship that's not the best who is just not into all this stuff. I invited the first best friend to go dress shopping with me and I think she'd make a great MOH and the other I've been friends with since we're toddlers so I can't possibly pick one over the other!! I'm still close with both. However, I don't really like the look of bridal parties, or bridal party photos. I don't really want to think about what dresses they should wear, and I don't really want anyone standing up at the end of the aisle with us. I just want it to be us, in a beautiful and romantic setting. I don't want anyone to have a job to do, and I don't want anyone having to spend money on a dress or bridal shower or bach for me, and I don't want to hurt anyone's feelings with who we choose. We are having 120 people to our wedding, all of our friends will be there, it's going to be amazing. I just don't know what to do, I don't want to be seen as "weird" but without a bridal party, I have moments where I could envision my two BFFs as Bridesmaids or two MOHs, and maybe my fiance only has his brother. Then I feel like if I have two MOHs, then he should add a groomsman, and then we basically may as well just have a whole wedding party. Either way, we should make a decision soon. What do you all think given this LONG story I just wrote!?? Thanks everybody, I just don't know what to do or how we can decide!
