For $10K, you can get a tractor like the one above, or you can get BX that is just a few years old. They are not nearly the same thing. All the tasks you listed are traditional Ag. tasks. You don't even need a loader (although they are convenient).
I think 2WD is fine. People used them for years and didn't know they needed 4WD. As long as you have decent Ag tires and properly
ballast for the task you don't need 4wd.
I recommend you look in your area for used implements first. Get an idea of what is available and which is a better deal in your area between category 2 vs Category 1 implements. Once you figure out what implements you want, then find the right size tractor for them. In some areas, category 2 implements actually are less expensive on the used market. I don't know your area.
You are doing ground engaging tasks so you will appreciate a heavy tractor. Most newish ~30hp tractors don't weigh that much and aren't on your budget. But if you do find this size tractor I agree with others that you should go with 4wd because it doesn't have the weight.
I have a 45hp modern (i.e. not that heavy ~6,500 pounds with ballast & loader) 4wd tractor. If I'm grading my driveway with my 8 foot hydraulic blade I can go as deep as I want with 4wd. In 2wd, I can still get the job done, but I need to limit how deep I go and take smaller bites (but totally doable). So ball parking it, go with 30+ hp 4wd or 50+ hp 2wd. I'm betting you can find a better deal in a 50+ hp 2wd and for the tasked you described, the large 2wd tractor will get more done than the smaller 4wd as long as you don't have space restriction or hills.
