Krita's Fill tool has a default Fuziness value of 80. The Contiguous Selection tool has 20. They are way too high. You can't select with that number, because it'll select EVERYTHING! This is a very common complain from new users, who often think Krita is broken because of that. By "80", did you really mean to "8"? Because Photoshop uses 8, and it was a pretty nice middle ground when I was using it.
Yea, I think a value of 8 makes sense from some testing.
To clarify, do you think 8 would also be fine for contig selection fuzziness? Or should it be something like 10 or 16?
I think 8 works best in both tools. Contiguous Selection with 16 Fuziness still selects too much colors that are obviously different. I think people expect Fill tool and Contiguous Select to work the same. Under the hood, they are the same in Krita, after all.
