Ceiling texture question barrage

So, I have a ceiling to redo. It was popcorn from the 80s, no asbestos. It had been partially scraped as in no high spots, but some areas are rough, some are smooth. And it looks to have been painted/primed over, after left smooth/rough.
The rough areas would be about 1mm thick, I don't think any are as thick as 2mm, however. Also, there do not appear to be any issues with damage or tape coming off.
I've been thinking about the best way to go over this. A few thoughts I have had were to 1) go over it with a thicker skimcoat to even everything out, then apply either some sort of roll-on, or stomp. Those seem like they would be slightly thicker to hide any imperfections that may linger after the thick skim. 2) sand the rough spots a little more to make them a bit more uniform, then texture. 3) sand all the rough stuff off, or sand it a bit, then wet it to remove the rest and get things really smooth.

So, that is the first area I have questions. Second would be about the texture itself. What should I use? How should I mix it up? I've seen mixing j/c with point. Some seem to talk just about using j/c. I have done 1 ceiling, it was smooth, and I just mixed in a sand texture into the paint and it seemed to work well.

3rd, texture types. I am leaning toward either a stomp of some sort, or roll-on. I'm not sure I want to try and learn how to work a hopper gun. So, what type of texture would be easiest, with less (hopefully) mess, that would cover well?
Now, I have seen knockdown, and that looks like it would cover well; but you roll it on, then smooth it with a knockdown roller. My question on that is how much pressure do I apply to the knockdown roller? Nothing seems to address that.

As I said, a barrage of questions! Hopefully, this wasn't all too jumbled!

It's almost always best to skim coat the ceiling after popcorn removal. Texture hides some but not defects. Except for minor repairs I always roll the mud on prior to applying a stomp texture - it's easier/faster that way. You take regular ready mixed joint compound and thin it with water. The thinner the mud is the lighter the texture will be, heavier mud produces a heavier texture. Neither is right or wrong - all about personal taste. It is important that all the texture mud be thinned the same amount so the texture will be consistent!

I've heard some say you can roll and then knock down the texture but I've always applied knock down with a hopper gun [and then knock it down with a wide knife]
