Sponge filters are good for bettas as well because they prefer slow moving water I believe

Sponge filters are a great option, just make sure it’s large enough. Don’t trust the manufacturer’s tank size ratings, get the largest one you can. The foam part should be at least the size of a soda can / beer can.
If you can get one with coarse foam, that’ll be easier for you to maintain because it won’t need as frequent cleaning.
HOWEVER, if you have not set the tank up yet, and you are open to using gravel (4mm diameter) as your substrate, consider another option: an undergravel filter. It’s very similar to a sponge filter but uses the entire gravel bed as the filtration medium rather than foam. They’re much less work to maintain, less visually obtrusive, and have even more biological filtration capacity. They are especially great for keeping the tank *looking* nice, because waste gets sucked down into the gravel (where it decomposes into free fertilizer) rather than accumulating on *top* of the gravel.
