I am very diligent, and the truth is that it is hard and it changes how you eat to be more countable. On a cut, it matters more. On maintenance, it matters less.
But most of it is a guessing game and making an assumption that it will all even out later. Ignore spices - you can assume 25 calories a day and it’ll still be too much.
Be diligent about oils. 9 calories a gram bites you quickly.
But ultimately, if you miss 100 calories a day, and are in a 500 calorie deficit recorded, you are still going to lose .8 pounds a week. And if that is consistent, adjust your portions and be fine with how you record.
And that’s the key - we know nutrition is variable. You won’t get it perfect. You just have to adjust for the imperfections.

And the thing is, you'll need to do this anyway - because you can't be sure in advance how many calories represents a "500 calorie deficit" for you, in your specific current conditions.
I was quite underweight in my youth, but I successfully reversed these kinds of feedback techniques to gain weight, and currently maintain what seems to be a healthy level. John Walker (co-founder of Autodesk, who passed away early last year) wrote The Hacker's Diet describing the basic technique. It's still live at https://www.fourmilab.ch/hackdiet/ .
