Can we create a list of alternative ETFs/ stocks to exchange for tax loss harvesting?

Given the downturn today and the general trend, tax loss harvesting has been on my mind of late. What do people think? A while ago I compiled a list of ETFs and their alternatives that would allow one to take advantage of the downturn by claiming losses on one's taxes. Can we use this post to compile a list of alternatives? Here is my tentative list for some ETFs. I mostly extracted this from some Schwab literature.
