Nice set-ups for climbing.
With 'bouldering', every fall is a ground-fall. It's fun. It's challenging. It's got every fall as a ground-fall.
Ropes are your friend, if you have to have good ankles to go to work, or something of that nature.
Auto belays are a double-edged sword. If you want to train, run 'laps'. No need for a belayer to stand around, neck craned, while you work stuff out or want to train endurance or speed.
You need a real human belayer to develop balance, like fine balance, as the Autobelay is always pulling on you. Too tight of a belay is detrimental to a climber.
Bouldering allows you to develop the balance without needing a belayer.
You can do well to develop your endurance and balance by traversing sideways, and going up and down to a reasonable height, without much risk of a bad ground fall, if you're good at falling well.
