Passed my private pilot check ride a few weeks ago and completed it under FAA Part 142.

Wanted to know opinions on what to do next. (Besides the instrument rating i'm doing that now.)
I was wondering if i should get my commercial through a single engine route first or start the multi engine way with a single engine add on later.
My current plan is to get my commercial single and then get my CFI. While working as a CFI, I was gonna get my multi add on.

What do you think is the best option?

I attend Embry Riddle Daytona Beach btw.
