Running my own fiber up inside the wall and through the attic. What to buy?

I had fiber installed a few weeks ago. The fiber that AT&T installed goes to the edge of the house. I want it to go to my master bedroom closet where the router SHOULD go.

I'm a big time DIYer and have fished wires many times in the my 40+ years of DIYing. I'm very confident that I can the fiber cable fished from where it comes to the house to where I want it.

I would like some advise on EXACTLY what fiber cable I should purchase. I would hate buy something off Amazon and then have the tech come out and tell me it's not compatible. Also, should I get something that has pre-terminated ends? Or should I run bulk fiber cable with no ends and the tech will take care of it?

Any advice on what fiber cable to purchase would be appreciated. The run will be somewhere just short of 100'.

And before anyone responds that I should just have the tech do it... I don't think so. This is going to be tricky and involve opening some walls and crawling in the attic. I don't think any tech is going to do this the way I want. :)
