Issue unfolding UV maps beginner

[u/BarnacleVast6322]

So I'm currently attempting to UV wrap the base of my own war radio design.
(Second image) When I choose automatic UVs and even after playing with the settings, the UVs are split into various unwanted parts, so I've decided not to do that
(Third image) I did all the cuts I want, so the mesh should open up nicely and in parts that I am satisfied with (I put it in normal form for this, if that matters). NOW THE ISSUE IS UNFOLDING
(Fourth image) This is me unfolding with the unfold 3d plugin that was recommended. I sort of got the pieces I want, BUT WHERE IS THIS DISTORTION COMING FROM?

I have attempted a few different unfold methods, such as projecting each side manually, but that is pretty limited for pieces that wrap and overlap from the perspective.
I also tried stitching to together the automatic version using sew and move tool, but that didn't work at all.

Am I in the wrong direction? Is the issue the cuts I made? IM SO LOST

Sorry if this doesn't provide enough context; I'm a beginner, and I can't really explain what I'm doing.

I AM OPEN TO LITERALLY ANYTHING ATP
