I use Splice to edit videos. While it's not as capable as Final Cut, it is fast, cheap, and just as effective in creating videos for TikTok.
Many creators struggle to get short-form content edited quickly and for a reasonable price. Splice allows me to make videos that reach a niche audience and move digital products. Here is a video I used to sell a digital download. It got 2700 views and ten sales.
I created another video with over 200k views, not targeting the sale of any specific product.
