Floorstanders vs Bookshelf

Looking for a bit of advice on whether a bookshelf or floorstanding speaker would be better. My room is 13’ x 43 but we sit only about 10’ away for TV watching (we could probably move the couch back a foot or 2 really). I’ve had some Dali Menuets on the wall and was happy with them but I want to move them up to another room. I tried some Monitor Audio Silver 300 and I like them when I am further out in the room working out or playing with the kids. But sitting down I find them giving me a headache, even at low volume. I listened to some Elac Carina speaker and found them to be more relaxing in the bookshelf version. I didn’t get to try the FS version. Any recommendations on what would be a better fit? My amp is a lyngdorf 1120.
