17 USC 101 defines a "work made for hire" as either "a work prepared by an employee within the scope of his or her employment;" or a long and restrictive definition of a work prepared by a non-employee under a contract declaring it to be one. The restrictions are important because under US copyright law the employer us the legal author of the work, and the employee does not have "moral rights" nor is the employee's life used to set the copyright term. (This is different in non-US countries.) Note that copyrightable work by an employee within the scope of US employment is automatically "work made for hire", and no employment contract is needed to make it so.
The term "work made for hire" is specific to copyright law, and thus anything not a proper subject for copyright would not be a "work made for hire", including most inventions, which are not protectable by copyright.
The term "work product" is not defined in the quoted part of th4e proposed contract, so I would take it to have its ordinary meaning "things, including documents, produced by a person's work".
Logically "such work product" which the contract purports to assign to the company is:
all of my work product, including materials, ideas, and other property, whether or not copyrightable, which I create with myself or with others relating to my employment with the company (emphasis added.)
Things not related to the employee's employment are thus excluded.
The contract provisions are as others have pointed out, poorly written. But they don not, it seems, attempt to claim rights in things not related to the employee's employment, and thus do not actually go beyond what a better-written agreement might well claim.
One way to deal with a poorly written agreement which an employee insists on having an employee sign, and which the employer will not modify the terms of, is to send a letter to the employer, promptly on signing the agreement, saying "I understand the agreement {title] which I signed today art your insistence to include [description of items included] and not to include [description of items excluded]" Sent by certified mail, or some other method which preserves a record of receipt, this would help establish, in case of any dispute, your understanding, and that if the company insists on some significantly different understanding, that the was no meeting of minds. Of course, one could decline to sign, but this will probably mean declining the job.
