Great suggestions! I'm always looking for alternatives to possible Russian spyware 😉 so getting FaceApp off my phone after trying it out was a necessary sacrifice…
In addition to the apps you've mentioned, I also wanted to share Hyperspektiv. It's not an alternative to FaceApp by any means, but it offers a lot of very cool/unique/interesting filters that can apply to both photos and video. And it's a "freemium" app, so definitely worth checking out!
