Nine exceptions on my title commitment. Which ones matter?

Your read on exceptions is right, that list is the carve-out from coverage. The sorting I'd do is between things that are recorded facts about the parcel and things that are open items.

A 1961 utility easement is a recorded fact. It's not coming off, and it probably shouldn't bother you unless it runs through the middle of where you'd want to build something later. Ask the title company to send you the actual recorded document and look at where the strip sits.

The plat restriction is worth reading in full, because subdivision restrictions can cover things like accessory structures and sometimes rentals, and if you're planning to rent the place later that matters more to you than the easement does. Whether such a restriction is enforceable and against whom depends on your state and how the plat was written, so if the language looks like it touches your plan, that's a question for a real estate attorney and not for me.

Standard exceptions like parties in possession are often the ones that can be removed, sometimes with a survey and an owner's affidavit at closing. Ask what it would take.

Ask for copies of every recorded document referenced in section two. They'll send them, it's a normal request, and half your questions answer themselves once you're looking at the actual easement instead of a one line description of it. The other half you take to a lawyer with the documents in hand, which is a much cheaper hour than the one where he has to go pull them.
