How strong is the connection to Aloy and her story lorewise?
I have talked with her only two short moments so far, but you will definitely meet her. I'm still early in the game, though, so no idea what awaits further ahead. She was in a group with few other people.
As far as I understood from the few articles that I read when they announced the game, you will meet few familiar characters along the way, but they are not playing any major roles in this standalone game. The world is definitely the "Horizon" world and you recognize the loot, tribe names etc, but the story apparently should not be related to main games. I can also be wrong here, since it has been a while since the lats time I read those and thought that I would never actually play the game. But personally I'm not expecting to have "Aloy game" here, or Horizon 3.

Story has never been the key point for me in Horizon games, so I haven't payed that much attention to details in it. It hasn't been bad, but it hasn't been anything super special either. What I mean with this is, that someone more story/character oriented person might find more connections between the stories than I do. The fun for me has been in combat and exploration, as it also seems to be the case with Call of the Mountain. It was still very nice to meet Aloy, though! And can't wait to see which other familiar characters I will meet.
