Respectfully, everything listed could be reappropriate for white people. In terms of stopping redlining, that would really only help upper middle class black people. There are quite a few HBCU’s with more white people than black. of the top of my head Northern Kentucky University
White People Are Becoming The Majority Of HBCU Students, Report Finds
How would ending racial discrimination in loans and mortgages be "appropriated" by white people?
How would protecting minority communities from pollutant exposure be "appropriated" by white people?
How would addressing the underlying health causes of Black infant mortality and Black maternal mortality be "appropriated" by White people?
How would H.R. 40 be "appropriated" by White people?
How would ending redlining be "appropriated" by White people. Ending redlining can help any Black person looking to create real wealth via home ownership because it broadens the range of neighborhoods they can move into and the stability of the investment. That HAS to be part of ending the racial wealth gap. Even for the Black folk not directly helped, having more Black folk with more stable mortgage investments vicariously would improve the state of the entire community.
I have a LOT of trouble believing that significant assistance for HBCUs will actually be appropriated by White people. The article you linked says that only 17% of students in HBCUs across the country are White and 3/4 of HBCUs are still 80% or more African-American. It also says that the main reason some HBCUs are accepting more White students is because of declining enrollment and revenue. If you gave HBCUs additional financial support AND made tuition free, both of which Sanders is proposing, then you address both those issues and schools wouldn't be pressured to accept more White students.
Hard to know what you mean that a federal jobs guarantee, universal health care, raise to a living wage, etc. would be "appropriated" by white people . Yes, white people would get them, but Black folk would too. Ending unemployment, non-living wages, student loan debt, housing and mortgage discrimination, and lack of health care insurance among black folk would all significantly increase the median $17,000 base wealth of the black community without having nearly as big an effect on the median $180,000 base wealth of the white community.
