-gg5 gives the second sense, but no examples of its usage.  i think they may be confused.
-vs unnecessary, as せんする entries have been added

GG5, 研究社中辞典

* Add [n-suf] – used as suffix (as in GG5)
* Add [vs] – seems to be used, given in 中辞典 （as 選をする）
* Add 撰 – frequently used, and AFAICT used pretty interchangeably with 選 (I see 撰 on food a lot, as in 和菓撰 (“select wagashi”) at FamilyMart, and on some nattō).
* I don’t know that there’s any difference in usage of 撰, so no notes/glosses to that effect – maybe a bit more used for poetry (per dicts), but it seems to get plenty of use in food, say.
