Erse used to have some videos online showing some of their inductors over various power levels and measured distortion. All of it is very low but there were clear differences between them. Air core was the best for distortion and their SuperQ showed the next best of the non-air core styles. The SuperQ also has extremely low DCR compared to all other inductors I've used. You can get them in 15 awg for reasonable prices in big values.

Decibel is correct, I honestly didn't even think about it. I just put the meter on it. My fault
Regarding the negative capacitance, the top answer in this link is helpful for understanding what your meter is telling you

Other answers are also informative.
And last but not least, hi from München
Made the move, ehh? I hope you get sick of seeing Porsches and enjoy Oktoberfest🤘🏼
Have not moved yet. Just visiting for a few weeks of R&R in the mountains and to see the inlaws
Stuttgart and Nürburg are bucket list destinations.
Heck, München was great when we visited.
