I don't know what this is off the top of my head. However, I would quibble with your description of a 4 quick & 2 slow cadence. Listening to it and looking at the sonogram, I hear/see a 3 quick & 3 slow cadence. I don't know if that helps.
My first thought was MacGillivray's Warbler because they do a 3 high & 2 low song, which can vary. I once chased a mystery singer at Ladd Marsh by LaGrande. It was doing a weird song over and over. When I finally saw it, it was a MacGillivray's.
Another thought: Hermit Warblers songs can end on a down-slurred "SEE-unk, SEE-unk." The ending of your mystery song sounds like that to me.

While birding at Ridgefield NWR, I heard a song I couldn't place. I
posted it as a mystery on xeno-canto, but so far no takers.
