While OP's question was about "size", and I almost got the NX450H+ but chose the RX450H+ for reasons that were nonnegotiable in favor of the RX to me: The eye-tracking ADS in RX which doesn't require me to keep hands on wheel when on long drives along isolated stretches of highway or as frequently as NX when in heavy commuting traffic (NX only senses the steering wheel touching) - the ADS has additional sensors and compute in the RX that Lexus "cost-cut" in the NX, and other minor but valued features such as audible alerts for blind-spot monitor which is apparently only visual alerts. I wish Lexus didn't do this cost-cutting in the NX, but I had to choose the RX because of these aspects as well, aside from lower cabin noise due to better sound-proofing.
(The above are from 2024 model-year, I'm assuming they are still the same)

The RX passenger side mirror doesn't auto dim either, at least in Canada. "Electrochromic Side View Mirror (driver side only)"
But I will agree that there is plenty of additional features and design differences to justify the price difference with RX over NX. The suspension on RX is magnificently smooth, it's quieter too.

The weight similarities between NX450h+ and RX350h are primarily attributed to the much larger and heavier traction battery used in NX450h+. Taking that into consideration, in Canada anyways, where we can do a simple selection of and Executive Model - which is an all options model selection, I'm seeing 4420 pounds for RX350h and only 3968 for NX350h, that's 452 pounds more. I would guess the RX has some additional body stiffening (more steel gussets and strengthening of chassis to make it stiffer and ride smoother) plus the size is wider and longer and there's some more bells and whistles too.
