How much weight can this support?

The Petzl ascension is certified to the EN 567 standard that says 4kN (900lbs) static load without destroying the device or rope. The key is static load. The device can withstand higher static loads to about 6kN (1350lbs), but any dynamic load applied from 4kN (900lbs) to 6kN even for a millionth of a second will eat your rope to shreds. The general rule is toothed cam devices eat rope at 4kN (900lbs), so don't use it as a rope grab, fall arrester, or progress capture unless you really know what your doing. The EN12841 type B standard tests show that it will handle dynamic loads over 4kN (900lbs), but it becomes very depended on what type / age of rope is used. Its a hand ascender for body weight (static loads), if your using it for something else consider another device.

Is this a practical solution for hanging my kids' rope swing to make it easily height-adjustable? Indoor use. 10.5 mm static rope.

No it's intention is too ascend rope, I see what your thinking but eventually the rope its hanging unto not the actual swings rope but what its holding would fail from being used in a fixed position.

What diameter rope is this for? ca i use it with 12-strand arborist climbing rope, 1/2" by 150' blue ox rope?

It will accept 8mm to 13mm rope - Arborist rope will be fine.
