Which template for a small business (subscription site)?

Hey guys! Just starting up my wordpress site (https://www.besociallyfit.com) and wanted some opinions on which templates are worth purchasing if you are aiming to have a sleek layout for a small business/subscription site?

I’m looking to feature video/audio for registered members for a small monthly fee.

Also, if you could have done it over again what would you have done differently with wordpress? Purchased a layout or went with a free one?

Thanks in advance!
