I mostly rinse my veg and don't worry too much about dirt, I guess I lightly scrub carrots and radishes. I've never fermented leeks, but they'd be a special case. I guess I'd cut off the parts I didn't want to eat -- the root end and very tops of the greens, slice them lengthwise and separate the layers. And then soak, rinse and spin, twice to get rid of the sand. And then ferment in their disassembled state. I've never washed anything so much that a bacterial colony wasn't still present. You could always tuck a cabbage leaf in with any other ferment just to be sure you're getting stuff going.
Any system you devise that actually works to keep your produce under the level of the brine is fine. I have some special-purpose glass weights and they're great sometimes, but most often, I just place a half-pint canning jar in the top of a quart- or gallon-sized ferment. I sometimes tuck a cabbage leaf in at the top, but that doesn't weight stuff down, it just corrals the bits and bobs so they don't go above the leaf. The jar above is needed to keep the cabbage down. But if you figure some way to make it work, it'll work!
If a little veg floats up around your jar/weight/whatever, it'll only ruin your whole batch if you let it. When you see it, pluck it out. Catching it before it molds is best, but sometimes they're tiny and you really don't notice. But once it forms a beach-head for mold, you'll see the white fuzz. When that happens to me, I take it out and compost that little bit. If it has enabled mold to form on the glass, I scrape everything off the surface of the brine and wipe the glass thoroughly, first with a dry paper towel and then with a rag dipped in vinegar. Then I'll put a clean weight/jar back in and continue the ferment. I have neglected a ferment long enough that I ended up tossing the whole thing, but not usually and not in several years. Minor pathogenic incursions are an occasional thing while tossing a batch is an extremely rare thing. But please know, many people are less cavalier than I am about this and we must each see to our own health.
