When to stop...

This is such a great post and is a common situation! My stats and situation are really similar to yours. I think you probably lost a lot of weight but maybe you lost some fat and some muscle, and want to continue losing fat without the scales dropping too much, and preserving as much lean muscle mass as possible so you get that toned look under the body fat. I don't know what exercises you're doing but lifting would be great for this. I followed a bodybuilding style programme during my weight loss and am at a "goal weight" now and pretty happy with how my arms and legs look as the fat came off but the muscles are in good condition. I still have some belly fat so want to stay in a small deficit for a while longer but. I'm moving country next week and have joined a powerlifting club there and am going to start eating around maintenance and lifting regularly without eating back too many exercise calories. This will keep me strong, keep the physique changing and the body fat dropping but the scales probably won't move very quickly in either direction.

At this point in my journey it's definitely more about a look for me than a number, I've proved I can hit the number on the scales but That's not why we're doing this is it! So I'm gonna keep working to achieve the body I want, we're not that far off and can achieve it for sure. So I'd say lose the scales now and focus on physique. It's great you love what you see some days, I think everyone has "fat days" so don't stress over that, it's amazing how far you've come that a few days a week you are actually happy with what you see.

If you're lifting as well, CICO is important but macros are quite important, please make sure you're getting adequate protein to aid your muscle repair and growth and carbs (even if it's just around your workouts) for energy and recovery.

If you need a training programme try a personal trainer, a strength and conditioning class or bodybuilding.com for ideas. At this point diet won't change much about how you look in terms of body composition, exercise will take a bigger role now. Well done on the weight loss so far and good luck!
