I see the Thames Barrier has several closures scheduled throughout this
year, but only one of them is a "full tidal closure." Is it worth trying
to go during the full tidal closure, or will I not notice the difference
going some other time?

Is "go" by land or water?

The river is likely to be closed for some distance around it during a
closure, so no trips are likely to run. 3 or 4 sections are often set
closed so the effect is visable on the greenwich-barrier-greenwich trip at
any time.
