Hi, this site may be helpful to you. Another trick is to place masking tape on the material you're cutting but it doesn't sound as that's a good idea for such long cuts.

You can use any thin kerf blade. Buy the one you will get the most use out of in terms of the number of teeth. No need for 100 teeth if your are cutting just a few sheets if you will never need that blade again. A new 20-40 tooth blade will work just fine. A few things to remember:
Good face goes down when cutting with a circular saw
Use a new/sharp blade
Support the plywood to prevent splintering
You can also use painters tape on both sides of the cut, but it's not necessary
More importantly than perfect edges on your cut is making your floor flat and fastening it properly. Clean cuts won't matter if corners or sides aren't even. Good prep will prevent mistakes from ghosting through your flooring material.
Here's a guide for different types of blades:

Here is how to avoid splintering: https://www.youtube.com/watch?v=zC2ZjxXz4h8
Without knowing what your floor is made of, and without knowing what the underlayment is made of, what material are you laying with, all makes it hard to answer your question. So, my recommendation for you is to go to an Ace Hardware (not Home Depot, Lowe's or Menard's) for advice. Take your saw with you. They will be able to talk to you and offer their expertise. That's what I would do. Best of luck to you.
If you’re talking about the underlayment that goes over an existing floor to apply tile on most of these are a masonry product and should be cut with a masonry blade.

A fine tooth would be best. Something designed for plywood or laminate is what we normally use.

Hi Have you thought to use a Bread Knife?
A finish blade like a plywood blade (many teeth) would be best. Put the top side of the underlayment down when you cut with a skill saw. The blade rotates such that it cuts from the bottom to the top. The top side of cut is where chip out happens. So if the sheet is upside down you get a clean cut on the bottom - which will be the top after you flip it over. Masking tape at the cut line also helps.
This may sound a bit strange, but painters tape is the best way to prevent splintering. Simply lay down a piece of painters tape where you plan to cut and remove it when finished.
