Yeah I would recommend a regular, good quality, Skil pattern circular saw over a track saw (which I believe is what you mean by "plunge saw") as a first tool along with a decent straight edge clamp.

Track saws increasingly come with things like riving knives, anti-kickback features etc. but a beginner is unlikely to start with large slabs of lumber but rather plywood, which is less likely to pinch in the kerf and cause kickbacks. And in the event that "woodworking is not for me" a circ saw is perfectly viable for carpentry tasks as well.

I do suggest avoiding anything that purports to turn a regular circ saw into a track saw. Just learn how to run the foot against a straight edge.
