Audience Building/Idea Testing on TikTok, Meta or INstagram

Hello! I would like to use TikTok, Meta, or Instagram to help me get feedback on specific product ideas for sub-niches or personas. For example, I might be building, or I might decide to build, a creatine for ballet dancers as a really stupid example. I'd want to utilize the best of these three channels to get signals on whether or not this is a good idea. From my understanding, video tends to work best on a lot of these channels and occasionally founder-led videos, but I'm not very keen on doing that as it's not really my expertise or where my interest lies. Are there any ways to effectively do this with static images or some other creative idea that doesn't require a ton of video content creation, at the very least on my end? I'm just looking for very quick and simple validation without needing to spend a lot of money. I'm okay with a small amount of ads, if that's necessary, just to test certain things. I don't want to be spending thousands of dollars or even really hundreds of dollars on ad outreach. Yes, I'm looking for somebody who has done something like this before on any of these channels and has a strategy that they can help with.
