I'd only go with a manual shift if you're going to spend long hours pulling a plow or other ground engaging equipment where the tad better efficiency of the manual would be to advantage. Doubt you're doing this with such a small tractor.
HST is MUCH easier to manage. I drove manual shift tractors in my youth and a 1970s one of my neighbors for a while before getting my own (HST) tractor.
HST does not stall out in low range. It will in high range if you push it beyond what the relief valve is designed for. Low range will pretty much hold it from rolling when the engine is off, but you also need to apply the parking brake.
HST is NOT an automatic transmission. It's a very heavy duty hydraulic system used in ships, tanks and other very heavy equipment. It's just a pump that sends approximately 3,000 psi fluid around to various systems: power steering, valves/slaves to make it go and FEL and 3ph lifts. Even with a manual transmission, you'll have all this but the valves/slaves bit to make it go. You'll never wear out a clutch.
