Lightweight wordpress site creation

I'd like to create a new website for my copywriting business. I'd like it to be fairly simple, and provide the ability for me to adapt it as my requirements change in the future. I've got a certain amount of wordpress knowledge, so am happy working with an existing theme, but it would take me ages to create something from scratch!

I've put together a pretty clear brief in this ppt: https://docs.google.com/presentation/d/13jpa4F8c9K8xkxq7kJAPnmEfltxxckii04rwdO-woQo/edit?usp=sharing

And my existing site is here: www.rockstarcopy.com - I will obviously want to transfer across urls, as well as code like Google Ads Goals.

I'd like to be sent the theme (or selection of themes) that's going to be used in advance so I can check it out.
