In addition to all you said, you mentioned your car...do they also pay you for your commute time? Of course not.

Say you have a 1hr each way...2 hours/day, 5 days/week, 48 weeks/year, $100/hr: $100 * 2 * 5 * 48 = $48,000. WFH literally just saved you $48k of billable time.

Buying a 4k monitor (that you can also use for non-work activities) on your own dime is probably reasonable.

There are specific carve outs in employment law and car insurance for commutes. Try using your personal vehicle for work with out additional have an accident and your insurer will wash their hands of you.
