5,000 units of apartments is not mixed use so unless there is more to the story you're leaving out, this is not mixed use.

5,000 units can also be built alongside entirely too much office space and ground floor retail, which is mixed use.

I’m not sure if you’ve ever been to Portland but the predominant problem is still too much office and retail space (much of it empty) and not enough residential space; every apartment I have lived in and almost every apartment building I walk by day to day has vacant ground floor retail.

That is entirely because there is no land value tax so owners are incentivized to keep the space empty.
