If the Senate got rid of the filibuster some really useful things could be done. Here are a few things that could happen without a filibuster.

• Get rid of the debt ceiling or at least increase it. Either would prevent a financial disaster.
• Support voting rights.
• Fix a bit of infrastructure.
• Pass a federal budget (instead of a series of temporary resolutions).
• Have a functional Senate.
• Have a National Bipartisan Commission on the January 6 attack on the United States Capitol.

There’s probably more but this is a good start.
