I’d say LST for your first grow so you can get a handle on the basics of growing like watering, pruning, knowing when to leave them alone. Once you have a handle on the basics and can see the plants growing steady every week without setbacks you can graduate to topping and other forms of HST in future grows. IMO, timing is everything with HST, top at the wrong time and you could set the plant back a week, super crop too late and your trying to crush a twig rather than a soft stem. Eventually you will utilize both forms of training in the same grow, but learning when only comes with the experience of growing healthy plants and occasionally making mistakes.
