Confused about how to market myself on my resume vs LinkedIn. Thoughts?

Hi, I’ve had 11-15 interviews and zero job offers this past year. Had to leave my last job due to harassment. Signed an NDA to ensure I’d get severance and solidify the narrative that I quit versus being pushed out. Didn’t want to deal with legal bills so I signed it.

I’ve had conflicting advice. My older sister says to leave that job off my resume and LinkedIn, and some say to leave it on since it was 7 months of work for a nonprofit.

I took the nonprofit finance program specialist role after a layoff where I got a raise but never a title change from specialist to consultant when I was doing consulting work with a CFO and controller, and prior to that I had an associate consultant role.

So my main two questions are:

Would you leave that nonprofit off your resume and LinkedIn?

&

Would you add consultant to all the roles and leave out “specialist” since consulting with clients and executives was what you did in those three roles?

I appreciate all input. This past year has been so confusing and I feel undervalued for working so hard. My confidence has been shaken up. I feel like I’ve tried everything.
