When you own your own web site, you may find yourself taking on all of the duties associated with it. This includes the design of your site. And the best way to make things as pleasurable as possible with this aspect of site ownership is in knowing which design and template to choose. You can choose to either use the free templates which may be offered by your host, or purchase templates. Doing the latter will allow you to retain the rights to it, which the former will not. Once you've decided on free or paid, it's time to think about your site's primary goal.
If your goal is to sell a product with your site, then you may wish to choose a template that offers lots of room for photos and some room for text. A more conceptual site will likely require a template that offers space mostly for text. Many templates from the best web hosting sites allow for their individual components to be deleted or modified. This can be true for both free and paid templates, but if you've paid for a template, it may make sense to save your modified copy as another version.
