Which trademark should I protect?
From the information you provided:
You have a brand name
You have a logo
You do not have a version of your logo that includes your brand name
Your brand name is (or will be) more recognisable distinctive for customers, than your logo
Your most distinctive trademark is generally the one that has the most value for you, and is the one your competitors are most likely to try to adopt or misuse. So it is generally the best one to protect first.
You should seek to protect your brand name
You can do that by:
Choosing “Word or Words” as they type of trademark you want to protect
Carefully typing in your brand name, making sure you do not include any typos
