How to Wrap Titles in Gallery Cards

You'll need to load some custom CSS in global Code for this. Try this and see if it is suitable:

.notion-collection-card.gallery .notion-property__title .notion-semantic-string  {
  overflow: visible !important;
  white-space: normal !important;
}

.notion-collection-card__content .notion-property__select {
  overflow: visible !important;
  white-space: normal !important;
  text-overflow: initial !important;
  display: inline !important;
}

.notion-collection-card__content .notion-property__text .notion-semantic-string {
  overflow: visible !important;
  white-space: normal !important;
  text-overflow: initial !important;
  display: inline !important;
}
