Netlify and Vercel would be my suggestions. They both have GitHub integration for the deployment.
I think it is a good idea to put some effort into the projects and host them on a proper platform as well. But they are fairly simple projects and their main purpose is to learn from making them, they won’t be all that valuable as a selling point. Although, a nice design might show some design skills I guess.
Can you explain the issue you had with GitHub pages a little more as well?
