No need to go to ATP.
There are enough opportunities to get picked up after you’ve completed your CPL/CFI.
I’d still recommend the CFI just because.
Find a local school you’re comfortable with and tell them the following:
You’re considering going all the way to your CFI but you’ll make the decision where and how to continue after every rating.
Don’t make the assumption you’ll be picked up by a Major.
No guarantees....
