It's going to depend very much on the features that your daughter used in capcut and what she will need. If it's their "AI" tools and tiktok filters, probably not. If someone knows of foss projects that have those I'd love to hear about them!
If she just needs a video editor that's free and powerful kdenlive is much simpler than getting into something like davinci resolve (which I would never recommend as a first step unless someone was very passionate about the editing process itself) and will give her the power to do pretty much anything you'd want, outside of proprietary filters or simple one-click tools.
Openshot seems fairly similar to kdenlive, maybe a little simpler. Check it out if that might work for you. I've never used it and can't compare.
Another one I have not used but is again MUCH simpler with fewer features but this may be a plus actually is Vidcutter. It looks like what I might imagine a FOSS version of Windows Movie Maker might be. Just drag clips in, cut them, mash them together, export. Simple, but not anything fancy.
So in order of least experience and desire to learn the software needed to most, I would recommend Vidcutter, then Openshot, then Kdenlive.
In order of the potential quality and variety of projects possible it's directly inverse.
Unless your daughter knows what ACES and REC 709 means then maybe point her toward Davinci.
