Reaching out to everyone you have worked above, under, and beside is the best strategy (assuming you are not the kind of person people don't ever want to work with again).
To put it another way, with ten years experience a hiring professional might reasonably wonder why you are cold applying rather than working through a professional network. Or at least networking into the company org-chart before applying. [1]
And because any public job listing is going to be fire hosed with applications by people scraping, the hiring professional's job entails saying "no" on more than 99% of applications.
Therefore finding reasons to say "no" is mostly what they are going to do for very practical reasons. You might be a diamond in the rough, but being in the rough is almost certainly a good enough reason to not move your application forward in a saturated channel of applications.
Good luck.
[1]: If you identify someone within, reaching out and asking for an "informational interview" is a way of opening a conversation. An informational interview is where you can find out what a company is looking for in candidates. You need to be fly fishing, not chumming.
