You can do 99.9999% with 5 tools - and something to support your pieces while cutting.
Tape Measure - You probably have one already, but it is worth mentioning.
Plunge Router & at least a 1/4" spiral upcut bit for round cutouts. Roundover bits, flush cut bits, straight bits, chamfer bits, etc. are nice to have, but not absolutely necessary.
Circle Jig - you can make your own, but having a premade makes things much easier, and guarantees you get the right diameter (provided you pay attention to things while setting it up) - definitely not absolutely necessary though.
Track Saw & a good finish cut blade
Framing Square - this is an absolute must for larger panels. The 3-4-5 method works, but a square take the guess work and math out of the equation.
You could probably even do most of it with just a circular saw, a straight edge, a jigsaw, a tape measure, & a framing square.
Even with flat packs you'll need a good amount of clamps for gluing, so I have not included those. You can use a finish brad nailer instead of clamps as well.
If you are going to purchase a circular saw, I would recommend getting a track saw. The WEN track saw I have is perfect for a hobbyist, and it is 1/6th the cost of a Festool or Makita. If you were doing contract work, or just wanted the best tools, the Festool or Makita are the way to go. But for hobby work, the WEN and a good blade will pay for itself in ease of accuracy and perfectly straight cuts within the first couple panels - in my opinion anyway.
My build game was elevated to another level by the track saw. I do also have a table saw, but long sheet goods are difficult to cut solo, so I use the track saw for that. Smaller pieces are definitely easier, faster, and more easily repeatable with the table saw. It is by no means a must have tool though.
Here's the last subwoofer I built (I still have to stain and clear coat it cherry to match my speakers):
