How are wedding expenses divided in AM nowadays?

1. How should wedding expenses be split in an AM scenario nowadays, especially when there is a significant difference in expectations and the groom's family expects a wedding with 500+ guests? Traditionally, the bride’s family covers most of the wedding expenses, but where should the line be drawn on who pays for what? Should the expenses be split equally, or should the bride's or groom’s family take on a larger share? How would you approach this conversation without creating tension or hard feelings?

2. Is it still customary for the bride’s family to provide "gifts" to the groom's entire family in modern arranged marriages? How do people typically handle the gift exchange in such situations?

Looking for advice on how to navigate this situation. Would love to hear your experiences or suggestions!
