I know it's some sort of jumping spider.
I would guess Platycryptus undatus, the Tan Jumping Spider.
That’s my guess too.
That’s a very interesting idea. I see how Menemerus bivittatus has wider dark markings and more of a marbled ‘turbulence’ pattern than Platycryptus undatus, which has a very uniform, regular pattern on its abdomen. This specimen does seem to match that – I really can’t argue with your identification.
