Are you going to build just a bunch of cabinets, or are you going to also do other woorkworking as well? A tablesaw is often a centerpiece tool and 'workhorse' for woodworking. Not necessarily the 'only' way to do things, but very-very-very-very useful for lots of different machining operations.
Full sheets of sheet good certainly can be awkward to maneauver through a table saw, which is kind of why the various track or circular saw sleds can be handy and useful.
Aww, hell, just go for the full-up cabinet saw with outfeed table.

If you are not going to be doing woodworking, then why are you even going to make your own cabinets?
Seriously, if you do not want to be doing a bunch of woodworking, then why would you go and build your own cabinets?
There are (as usual) several approaches to building cabinets. Biscuits, cleats, dados, grooves, rabbets, raised panels, rip cuts, crosscuts, pocket screws, dovetails, carcass construction, drawer construction, drawer slides/glides, rail and stile construction, clamps (always LOTS of clamps), table saw, radial-arm saw, power miter saw, sliding miter saw, circular saw with a guide-rail system, dust collection, router(s), router table, router bits, saw blades for the various saws, etc, etc, etc. Not all those are always needed and there is at least some overlap in machine capabilities and techniques, etc, etc, etc.
Not rocket science or brain surgery, but decent cabinets are not as simple as just hack some sheet goods to rough size and slap them together with 6D nails either.
