I love your new word, Kisal!
invefestive = invasive + infestive. Just so!
There are lots of other bright cheerful yellow flowers in about that size range. One of my favorites is sundrops (aka Missouri evening primrose). It's native for me, but I don't know if you have a native version.
Other possibilities would be coreopsis, celandine woods poppy, california poppy (an annual, but freely re-seeds in the right conditions), sulfur buckwheat, sunflowers, black eyed susans ....
But I love the buttercups too and have been known to leave some, just keeping a close eye on whether they are spreading.
