I asked my students in 1st year engineering what kind of video software they used to record and edit videos for homework and projects. Here's the summary:
Of these, iMovie, YouTube, OBS, Clip Champ (another link) and DaVinci Resolve are the favourites.
I've found that there are other suggestions, including some on Reddit.
Students may wish to investigate some other contenders, including OpenShot and Filmora.
Personally, I use QuickTime for some projects, but usually Camtasia. Unfortunately, Camtasia is not free. When I was a student I was a big fan on iMovie and would likely use it again if I wasn't using Camtasia.
