Editor/Author - Registration as Activité Commerciale and Activité Libérale ?

Valerie you are kindly setting up my Micro Entrepreneur for consultancy activities as we speak. 
My wife will also soon be using your services to register as an Micro Entrepreneur, albeit for a combination of services and products. The business will be providing services and selling products to writers/authors and readers within the Mystery genre. This will be as an individual working from home, using an ecommerce website.

Services: Will include editorial services for authors (story/structural editing and professional beta-reads). 
Products: Books; self-published ebooks (digital), paperbacks (physical). All paperback orders fulfilled by a third-party, ‘print on demand’ service. Sales will be both direct via her ecommerce website and available through other online retailers such as Amazon, Apple Books, Google Play Books. Income from these other online retailers, although self-published would still be classified as ‘royalties’. Also will offer printable digital downloads such as PDFs (worksheets/planners), primarily aimed at writers. 

Future: Possibility to expand/diversify (remaining within the Mystery genre) into merchandise such as clothing, mugs etc (from a third-party ‘print on demand’ service such as Printful or Printify), and audiobooks (digital downloads). 

1. Will the above combination be possible for an Micro Entrepreneur ?
2. Would this require registration as Activité Commerciale and Activité Libérale ?
