You're right in that there were some things that could have been achieved with bipartisan support.

One example would be eliminating the per-country limit on employment-based immigrants, which has resulted in 100+ years of wait time for India-born EB2/EB3 aspirants. There's bipartisan support for it, and it might have passed in isolation, but it wasn't high enough of a priority for either party. (Note though: the provision eliminating the per-country limit was included in the S. 744 bill.)

For the most part though, Republicans opposed nearly every bill that Democrats brought up. The likelihood of anything meaningful / highly-impactful / substantive through Congress, in the face of adamant Republican opposition, was unfortunately fairly low.
