@lemdro.idAlways worth mentioning the free version of davinci resolve. It's feature complete for your described needs, doesn't hassle with things like watermarks, and the tools are great if you ever need to step up to something a little more robust.
And for how expensive portable consoles can be, I'm not calling anything a "steam deck killer" until I'm also confident it can be repaired and upgraded for years after I buy it.
