Best editing program for Fortnite montages?

I started playing fortnite again. And wanted to do Mondays too. I know from myself how I create good films but not really montages with fast, massive and above all striking transitions and effects.

Can someone please recommend an editing program where everything such as transitions and effects is already given (except Filmora) xD.
IMPORTANT: No watermark, please

Spontaneously I would like to call Davinci Resolve or ShotCut.

Montage / Compositings: AFX or HitFilm Pro, but they both cost and are not easy to learn.
