A floor stander like the Paradigm Personal 3F with a super warm amp. Something along those line. I may have misspoken when I said a floor stander could work great. I was assuming the clear listening space was 13 x 21. I now think that is your overall room size. Your fellow Canadian Mitch Barnett can make almost any floor stander work in your room. I speak from experience.
If you like classical music, then the LRS+ is what I would try first. It will have a bigger sound stage and depth than any bookshelf. The French brand I mentioned may have a better driver, but for a small space the LRS+ is amazing.
The KEF LS50 Meta + KEF KC62 sub were great but the soundstage is smaller than the LRS+. The Yamaha NS3000 will have the very best driver from anything I mentioned. Maybe the best in the world for a cone.
I use the KEF KC62 sub with a crossover setting at 50Hz for the LRS+. It is hard to beat this in a small space at any price.

Here is another option that will sound better than anything else in a small space (no room to deal with). I use this for late night listening while I work.
RAAL 1995 Immanis (I use the older phones, until I can afford the Immanis)
BTW - I have photos of my office in the link provided that show LRS+ | Thiel CS3.7 | KEF LS50 Meta.
