This sounds like bikeshedding. I also wonder if this is really about camelCase vs snake_case etc, or is there something else going on that is being battled out through these irrelevant things? This might be more of a personal/team issue than a technical topic, and if it is you should focus on solving that.

But if it really is a technical question I would suggest to try to make the most objective decision possible, so list your goals, list pro/cons of each option, make a decision matrix, decide, move on. If it's purely subjective a vote could work, but then someone might lose, idk how well that does, I would just go with the "mainstream" option.

The other option is for you to just decide and take the conversation to goals; I assume you are trying to build something and most of the things you describe will not impact the end result in any way. Motivate people to focus on the things that make impact.
