Running into an issue I can't figure out. In essence, I have a page that has some text, possibly some equations, a couple graphics and maybe a table, all separated by flexible white-space. Sometimes everything fits on one page, but sometimes the graphics are too large so multiple pages are needed.

Let's say I have 3 graphics. In the case they're all to big to fit on one page, I'd expect that the first two graphics stay on the first page, distributed evenly along with any preceding text, and the third graphic would be on the next page along with the following text or tables, etc. However, my code always keeps all three graphics together.

I'm of the impression it's due to vspace creating an unbreakable vbox, but I don't know how else to handle what I want without manually adding a clearpage or similar. This is undesirable; the end goal is templates that pretty much automagically do this for me, of course!

Here's a MWE. In this example, images A and B end up on page 2. My desire is for image A to end up on page 1, and B, C and the next section on page 2.

You get slightly luckier with centering but really the issue is using \* rather than proper sectioning or item commands. In the scope of centering (and center) \ is really par rather than its usual definition of newline that means it exercises the page breaker, \* adds a nobreak penalty, so if it happens that a page break is considered after the heading a break is prevented there because of the * but a zero penalty break is available before the first image due to the vfill being available to fill the space, so TeX takes that page break rather than looking ahead.

A perhaps better markup avoiding using explicit spacing font changes and \ in favour of the more idiomatic latex caption markup would be

You can use the facilities of the float (and related caption) to customise the caption formatting as required.

I am not sure what you mean "flexible white space" but you could define a new command that would use vspace with a predefined "flexible length".
