I've done a fair bit of floor sanding over the last few months.
I found the guide @Bobbo wrote on here a really good starting point, as well as the videos from How to Sand a Floor which explain the methodology really well, including why you need to go up through 4-5 different grits, even though it stops making much visual difference and starts getting less and less rewarding.
Agree with the points already made about edging sanders and Osmo Polyx.
I would also add that if you're going to go all in to do it, it's probably worth spending a bit more to hire a Bona or Laegler sander - one of the How to Sand a Floor videos explains why but I think the dust extraction is another reason - I found them almost as "dust-free" as they claim to be.
Also make sure you've got good ear defenders and a respirator.
