> many-to-most of these clauses are in every boilerplate contract
Contracts are entirely negotiable. If there's a job you want, but the contract contains an objectionable clause, tell them that you're willing to accept if they strike that clause. If you're at the point in the hiring process where they're showing you the contract, that means that they've sunk resources into you that they don't want to throw away. And the fact that these clauses are boilerplate, as you say, works in your favor, because nobody involved in the hiring process consciously chose to put that clause in and they probably don't really give a damn.
