I wondered about the L. Again I'd personally go L3302, a bit more power, brakes on the left.
I'm also not as convinced that a mid-PTO is critical for resale. I figure that you're not in snow country as you said little snow work and no snow blower (so not many people will want a front snow blower), and you're not buying a MMM. So whoever buys it presumably isn't mowing, otherwise they'd buy one with a MMM on it. If you don't want/need a mid-PTO, stands to reason there'll be other people around you who have the same needs when it comes time to sell.
The reality is that all these tractors will do what you need, and all will be a massive improvement over doing work by hand. A BX in my opinion is a bit small to run a flail or a rotary cutter, and limited in lift capacity. It also is limited in ground clearance, so for woods work I think not ideal. I owned one and upgraded to a B2601.
The B2601 is what I have now, and is a good machine. It will do everything you describe. But you asked if an LX might do it a bit better, and indication is that money isn't a big constraint for you. In that world....yeah, an LX would do it a bit better. And an L would do it a bit better still.
Given that all the machines will do what you need, you're down to either one having a feature you need or feeling better to you. Sounds like nothing there to worry about. Then there's consideration of regrets. Will you regret not getting a slightly bigger machine? Will you regret getting a machine that's bigger than you really needed, and your neighbours are all whispering about you? To be honest, I doubt either of those will be a problem - they're not that different in size, and an LX isn't too big for 3 acres. To me the fact you're asking the question means that you would kind of like the LX. So what is the barrier that is holding you back? Because asking the question means that you might have regrets if you don't buy it.
