For me, "circus troupe" is nothing new. I've been playing for 35+ years, and even "back in the day" we had parties that were filled with what we might call unusual. I played a centaur back in the early days of a 2e game. We've also had parties of, say, all dwarves. It's run the gamut.
And that bit there about "what we might call unusual" is worth remembering. If a fantasy world, or even more so something like the Star Wars universe where there are thousands upon thousands of different species, a diverse conglomeration isn't going to seem all that unusual. Especially, as Charlaquin pointed out, to be an adventurer (or mercenary, or...) is already pretty darn unusual. Most folk would prefer to stay at home and not die, thank you very much. Adventuring is already going to call for the exceptions.
That might be a framing that for your mind can make it easier to get on with.
You also asked for moving past it, and for that it might be worth looking about what elements of an all "more mundane" campaign you feel are missed out of a diverse cast of unusuals. What thematic bits, what narrative bits, etc. Is it the "everyman makes it big?" or a greater tie to taking up action in our modern world? Is it a nostalgia or desire for a certain aesthetic? An overall difference in genre/tone? Once you get what you feel is missing for you, that can be the place to lead with during your next Session 0. Maybe those genre/thematic/narrative/focus bits can be introduced into the campaign without having to develop a world without circuses. Or, maybe by framing it that way everyone is intrigued and enticed to play in such a world.
As there is most certainly nothing improper about either style of adventuring group and campaign. And we all have our preferences. If our preferences aren't being met, we can choose to bend them to stay in the group, and/or choose to invite others into our preferences, and/or choose to find another group that already shares them.
