Is there an method of using a moving part in an assembly to produce a mated-cut (with clearance) as either part is moved into/through the other?
I'm not aware of any.
Are you looking from animation perspective or permanent cut?
I mean are you looking for the cut to appear only when you move the part or you need the cut based on the motion of the part?
I'm looking to create permanent cuts using that technique. I have an assemblies which has complex part-motions wherein one mated must pass into another (as illustrated below). The slotted-tongs follow a peg inside another part which needs voids to accommodate the tongs' motion internally. I roughed-out a solution, but am incredulous that there isn't a standard SW-solution that can easily accomplish this that I'm just overlooking.
Yes - I have never found a nice way.
Over the years I have kludged together various solutions.
Here (at master part level) I used derived sketches - some of the sketches were constrained, others partially constrained so I could observe movement.
Other times I have copied surfaces into my part from the assembly
and done feature specific solutions generally involving direct editing.
Note all the body moves and sketches
Other times I have been unable to find any solution.
What methods to acheive a rough path of the slotted follower are you already aware of? I can think of quite a few ways to get this done. Some more accurate than others.

I would create temporary mates in 3 positions (each end of the slot and the midpoint of the slot) and convert entities, then lock the references of the extreme position on the slotted follower. use those 3 sketches to draw an arc or spline for a material removing guide.
now that 2019+ allows you to lock external references for individual sketches you can keep it in context for future design revisions
It's not dynamic, you have to press Ctrl+Q at each pivot bar position.
It uses an assembly level extrude cut with a sketch that's coincident to the bar's leading faces:
EDIT: Perhaps combined with a motion study, this will get you what you're after.
EDIT II: I forgot you mentioned clearance, too. Offset the sketch from the bar for the clearance and make the extrude cut a little wider for the clearance in that direction.
I'm not sure what you're trying to accomplish, SW isn't a physical machine etc. Even if it would be possible to do, you'd need to oversize the arm dimensions before it would be manufactured, with the proper clearance for this to work in the field. All you need is to create a Master Sketch/Skeleton Sketch Part (SSP) using that design process would give you proper parts at the end of the day.
For what you have in your gifs...easy. All you need are a couple sketches in your pivot bar part which you will then use as derived sketches in the plate (be sure to constrain them to the sketch it is derived from) to create a swept cut. (Not as easy as other CAD systems that allow you to create & designate "cut bodies".)
