For drawing up, I go with 2213’s plus 3ml syringes fitted with 25g 1.5” needles. Being able to reach the bottom of the vial is what the extra length gives you, so pulling out all of the liquid is simpler.

With a 25g, the puncture left in my vial seems huge, so I moved to 30g. Either one should probably do the job, correct? There isn’t any particular advantage a 25g offers compared with a 30g, is there? It just comes down to what someone likes?

The variation in dimensions isn't as large as you'd expect, and the diameter of the "hole" is irrelevant since re-using a vial after extracting the liquid for filtration is something you should NOT do—doing so would defeat the whole point of filtering.

Yes, I do run it through a filter into a fresh sterile vial, but the puncture it makes in the stopper seems larger. Perhaps the vials I'm using aren't the correct ones.
It seems like the needle you use to draw the contaminated solution is the same one you then use to push the filtered liquid into a sterile vial — which defeats the purpose of filtering all over again.
In the quoted post above, Vash was recommending a 25G 1.5" needle specifically for DRAWING the solution out of the vial.
For injecting the filtered solution into a fresh sterile vial, a brand-new sterile needle should be used, and the gauge you pick is up to you (once more: going from 25G to 30G changes the diameter by .008"—eight THOUSANTHS of an inch—which makes no difference at all with a modern self-healing rubber stopper, so there is no reason to fret about the size of the "hole" left behind).
