Depending on the absolute value of "all costs", I'd prefer #1, or a combination of #2.
For GLAM (which is what I am mostly involved in), monthly page views would suffice, and those should be easily done in MySQL.
Daily views would be nice-to-have, but do not reed to be in MySQL. [...]
I'd second this. We have partners (but also, say, internal WikiProjects) working on a long tail of tens or hundreds thousand pages with their own project: cutting this long tail, including redlinks, would be a higher loss than a decrease in resolution.
