My neighbor has a "garden tractor" that works well most of the time on his 2 acres of grass. His place is almost entirely flat. Your place is a) larger and b) far more uneven. Your situation is simply going to overwhelm a "garden tractor", so each mowing will consume many hours of your time, the machine will wear out quickly and dealing with your slopes will be far more dangerous than it should be. The others have provided good advice. Reality check: You need a serious piece of equipment to do your mowing and you need to acquire the skill to operate it safely on your place.
A "subcompact" is built low to the ground so it is more stable than a conventional tractor, it has a heavy-duty drivetrain and 4 wheel drive to handle your hills without strain, you can equip it with farm-type tires that have more traction than the turf tires on a garden tractor, it has seat belts and a roll-bar to protect you if the worst happens, it has automatic drive (hydrostatic), power steering, cruise control, and other amenities and it has a diesel engine that will last about forever with a little TLC. There are some other ways to go, but a subcompact would get my vote.
Don't know if all this is what you wanted to hear, but this is an important decision for you. We all want you to make a thoughtful, knowledgeable choice.
By the way, when my neighbor's garden tractor won't climb out of his one small ravine because the grass is unexpectedly a bit wet, I go over and pull it out with my subcompact.
While I think a subcompact is a good choice for mowing projects I don't see them as being much more capable than a good garden tractor such as my x749. I think you have overstated the difference between a subcompact and a garden tractor.
I do feel that a rops and a two range transmission on the subcompact would be good reasons to make it a better choice. If I were to recommend a tractor for this work and slopes it would be a new small compact tractor with two or three range hydrostatic, 4x4, filled tires and wheel spacers. A wide and low stance would be the most appropriate choice imo.
Those slopes look to be difficult and dangerous for a newbie, I recommend getting some experience before tackling them and it would be advisable to have someone standing by in the clear to get help if needed.
