I decided to focus on relative fat mass rather than weight. Body types can vary so much with regard to weight and most bariatric clinics and insurance companies still use BMI, which is a complete BS system with absolutely no scientific validity. However, there is a lot of research about the effects of body fat on the body, so I chose to look at that.
The weight goal that I usually list is just a guess of where I'll be percentage wise. If I was going my most of the weight charts out there, I'd have to get down to about 158 or something, which is 20lbs lighter than I was when I was in the Marine Corps and in the best shape of my life at age 20.
I'm currently at 220 lbs, and my relative fat mass is 25.11 - which is just above "average." My goal is to get below 19, which would put me in the "fitness" category, but I'll certainly be happy to be well within the "average" range and not the obese range.
Relative fat mass is easy to calculate based on height and waist circumference using this calculator:

Studies have shown this to be way more accurate than other weight charts, and even similar accuracy to a body scan. It matches almost exactly with my scale that tracks body fat, which also matched up very closely to the body scan I get when I visit the bariatric clinic, so I feel pretty confident about the numbers and basing my goals on that instead of weight charts, per se.
I may not even need to get into "onederland" and be in a good range for me, although I suspect to get to the "fitness" level, I will probably need to be under 200 for my body. Other people will be different, obviously.
