Congress passes plenty of laws. 95 so far just since the last election: https://www.congress.gov/public-laws/119th-congress Last congress passed 274. It's really only the controversial stuff that gets gridlocked.
The problem is that our government is now so large and complicated that it's simply no longer possible for Congress to effectively set policy for all of it. (This would be true even if they weren't so polarized.) So instead they just keep delegating more and more power to the executive branch.
The Administrative Procedures Act, Congressional Review Act, and the recent overturning of Chevron are all good checks on executive/agency power here, but I don't think any of them solves the fundamental issue that the executive branch was simply never designed to wield this kind of power. I'm not really sure what the right solution is.
Two-party politics promotes gridlock. Multi-party systems, as long as they don't have veto players, don't have as much stagnation and do a better job of citizen representation.
Do they? 79% of Australians and 73% of Germans have an unfavorable view of Israel, in Germany's case 49% of all being "very" unfavorable [0]. Don't see much representation of that in their politics. Both very much multi-party systems. Australia's system in particular has aspects that are often held up as one of the best in the world. Even on important other topics, it doesn't seem to reflect things much.
Another example, if you survey basically any multi-party European state such as Germany, Belgium, the Netherlands, Denmark and so on purely on economic policies, you'll overwhelmingly find people supporting much more progressive taxation and in general more socialist economic policies. I'm talking large majorities. Including nationalization of many institutions and so on. Yet their governments have done the direct opposite for decades. Not very representative.
The better representation you're talking about is very surface level, for everything that matters the outcome is that favored by big capital.
