Wedding party help

Hi everyone, I could use some help with determining my wedding party. My wedding isn’t for a while, but I just figured it would be best to go ahead and figure out the wedding party before planning anything big.

So, my fiancé has determined that he wants his best man and two other groomsmen. Which is fine, but as of right now I only have my matron of honor and bridesmaid. I don’t have another person to make it symmetrical. I don’t have many close friends who are girls, so I’m kind of at a loss as to who else should be in it. I thought about asking a girl that I used to be best friends with. No bad blood or anything, we just chose different colleges and different paths, so we don’t talk much anymore and aren’t super close. I also thought about asking another friend of mine where we aren’t as close as we used to be, but still close. However, if her wedding goes as planned this summer, she’ll be moving like 10 hours away. And I don’t want her to be a bridesmaid living so far away because I don’t want her to feel left out or feel obligated to come back here and help plan and be a part of the fun stuff knowing she’ll have to travel so far. I just don’t want such an inconvenience for her.

So I don’t really know who else to ask since the rest of my friends are either men or are just work acquaintances. Do I just be asymmetrical? Or should I invite someone else? I don’t want to tell my fiancé that he can’t have one of his friends or brother in the wedding just so that it would be symmetrical, it’s his day too.

And I also have another question. I was the maid of honor in my best friend’s wedding as well as my step sister’s wedding.I’m close with both of them, but I don’t know who to ask as my matron of honor! I’ve known my best friend longer, but I kind of feel obligated to have my step sister as my matron of honor. Like I feel like it’ll upset my entire family if she’s not it. But I just feel like my best friend knows me better and I feel like we’re just closer. I really don’t know what to do.

And this is the same dilemma my fiancé is having. He’s closer to his best friend but feels like it would be upsetting if his brother isn’t his best man. We could really use some advice please!
