Well, I seem to be where I
can be, naturally anyway. And although I wouldn't mind getting a bit stronger and adding a couple more pounds of muscle, I'm not complaining. If you've been at it long enough, at a certain point in middle age it becomes about maintenance.
As for your doing more sets to get both stronger and leaner, I fully understand the rationale (and lived by it for years), but the research seems to indicate that most people tend to overshoot on volume beyond what is necessary. I won't pretend to know where the volume sweet spot is. But I can tell you that I'm doing a lot less volume than I used to a few years earlier, and I don't seem to be regressing. And up until the point where I dropped the volume, I was no longer progressing either. So, in retrospect, all that extra volume
appears to have been superfluous. I should point out, though, that intensity was always very high, so that part has been a constant.
You mentioned using lighter vs. heavier weight. Have a look at this site; I think the piece will be worth your time:

As an aside, I recall from one of your earlier posts that you spend a fair amount of time in the gym and do a fair amount of cardio. Keep in mind that doing too much can be counterproductive even in taking and keeping fat off. So, again, the relationship between effort and results is evidently not quite so linear. (I wish I knew the cut-off point, or at least the marginal rate of utility.) Some food for thought from a few links on the subject I came across after a cursory search:
