I would go with including the keyword in the username so long as the example was similar to what you used in your post. I am currently using Instagram to find accounts in a certain niche and it’s much easier to find them (and instantly know what they do) when they include the keyword in their username.
I would consider also using an alternate keyword in your name so long as that keyword is very similar. For instance Matt Steinman - Marketing Expert
You can change your username whenever you want
