Let go from LO cross-asset seat. How to position next move?

Reposting in Equity Research to see if it gets more traction...

Recently let go from a long-only cross-asset research role after ~5 years. Sat between research / PMs / sales / tech (yes, aware that's a lot of different areas), certainly not a pure coverage seat alone. Background was more quant-focused (STEM undergrad) before taking my public markets role.

Role evolved a lot over the past few months and expectations shifted. Unfortunately, I had a few visible misses during that period. That, combined with both broader firm + team organizational struggles, ultimately led to the decision to exit. 

Trying to be pragmatic about next steps:

1) Given this background, what roles make the most sense? Ideally would prefer to pick one or two of these and really dive in rather than spamming applications all over the place. 
Considering:
-Equity or credit research (either LO or L/S) and ideally something with explicit coverage
-Quant-focused data-driven investing roles, but I don’t have a PhD, which I am aware is typically expected for quant research
-Finance adjacent roles at corporates (e.g., strategy, IR, corporate development, etc.), which I have seen people move to after getting experience in LO

2) How would you frame this exit externally?
Current thinking: I worked with challenged platform with shifting expectations and ultimately found myself in a place where I could not grow at my best. I’m looking for a seat with more exposure to true investment decision making. 

3) Where have you actually seen profiles like this land successfully post-reset? 
Trying to optimize the next move and avoid repeating the same setup.

Side note: just scored 715 on GMAT Focus couple days ago, and currently doing a late-cycle B-school but aware that likelihood of acceptance at top places is super low. Any thoughts there would be appreciated. 

Happy to add any more context, but trying to remain somewhat vague for anonymity purposes
