Electrical – How to switch a ceiling fan to a regular light fixture

You probably should have paid more attention to what was connected to what. In all likelihood, the "sw" bundle has a wire that was carrying hot (power) from the unswitched wire at the fixture to the light switch, and the other wire was returning that power from the switch. The switched wire should be but often is not re-colored red in that application (ie, a back/white/ground cable running to a switch should have red tape or paint on the white wire ends if it's a "switched hot" rather than a neutral.)

That does not meet current code (which requires a neutral wire at the switch) but met older codes and was very common (a switch loop.)

As such, the expected configuration that will probably work if things are wired normally would be cable blacks together, white from unswitched cable to white on fixture, white (recolored red for clarity) from switched cable to black on fixture, and grounds all together.

Odd that you said you had a white wire that was hot. Both white wires should be neutral and have no voltage. Seems to me wires would go like this: connect all black wires together. That will run hot all the time to the fan as well as sending power downstream. Next tie all white wires together. That will provide neutral to the fan as well as pass neutral downstream. Ideally there would be a bare copper wire coming from the hot side and another to continue downstream. The red to blue should switch the light, providing that blue is the correct one for the light.
