Interesting set of names. To me the best three are resets, freedoms and crushes. I can't answer your question, and you may already have done this, but here are the set of .io sales in NameBio in last 2 years that ended in s. By no means all are comparable, but some are and this may give you some idea of a pool of mixed wholesale and retails names.
Here is list.
Of the others I like flashed the best.
For wholesale sale, there are not infrequently people on NamePros looking for single word .io, and you could try a few of them.
Best wishes for them.
