Can anyone tell me what this white fluffy stuff on the top of my soil is? And if it’s more than a cosmetic issue, what should I do?

It’s not harmful for most part, means your soil is too damp, possibly not enough airflow around plant. I would remove it, spray with hydrogen peroxide and sprinkle cinnamon on top of soil after doing that. It’s mold.

what debbie said. it’s not necessarily harmful to the plant, but usually means your soil is staying moist for too long. to fix it long term, I’d repot into a chunkier potting mix with more drainage and let the plant dry out more in between waterings, but I can’t say how much more precisely without knowing what type of plant it is. If you repot, check on the roots as well to make sure there aren’t any mushy/dead roots. If there are any mushy or dead roots, you can trim those off with clean scissors and spray the remaining roots with 3% hydrogen peroxide before putting back into chunky, well-draining soil.

mold. scrape off affected soil and sprinkle with unsweetened cinnamon. works perfect for me. if it continues to be a problem, spray the soil with neem oil.
