As long as they can find some “cause”, then you’re fired and ineligible for unemployment benefits.

This is a common misconception, and everyone should apply for unemployment if they lose their job for any reason, including if they quit because they felt pressured to leave (constructive dismissal).

They need an actual good cause, like actual damages to the company or something, and they need to be willing and able to back up their claim that you are ineligible, or the unemployment offices will side with you and award it anyway. They generally favor employees over employers in decisions, because they know the bullshit companies do to not pay out.

Lose your job? Apply. You have literally nothing to lose.
