Other than the obvious seedpod are there any signs of successful pollination?

Hi there. If you are watching a plant closely, you will be able to see the difference between unpollenated and pollenated ovaries. The unpollenated one doesn't usually swell. To see this difference you can prevent the possibility of pollenation by removing the anthers from a flower, and then make sure that one close by does get pollenated.
Now watch the one that did get pollenated, and make frequent comparisons to see the difference. Generally speaking, the mg flowers that didn't get pollenated, perish quickly and are replaced with another candidate quickly. This swelling usually only takes a few days.

Some species benefit more from pollen, foreign to the single plant the flower is on , and have methods to promote foreign pollenation. ie,
the pollen and the ovaries are not ripe at the same time, in the same flower. Using this tool, a specie can hold that pistil up that stays ready for a few days, in order to obtain foreign pollen, recently collected by browsing nectar feeding pollenators. There is an old saying that two heads are better than one. With some floweres, two different sources of pollen are better than one. Frank
