The harbor freight 2-ton compact trolley jack with 12 3/8" doesn't have enough height to pick up both wheels via the center jack point, but lifts the RX350 enough for a quick oil change. It does fine jacking from the lower control arm but limits you to one corner at a time. https://www.harborfreight.com/2-ton-...ack-64874.html

We've also got a low-profile 3-ton Daytona, but it's 79lb so keep that in mind if you don't have a garage and need to lug it out for maintenance work. It has a maximum lift of 19 7/8" which is more than enough when lifting from the center jack points.

My Harbor Freight Pittsburgh Heavy-Duty 3-Ton Floor Jack will easily do it (used it today to change the oil & filter and rotate the tires on my wife's 2015 RX350 FWD). The owners manual shows a maximum lift height of 19.75 inches. I purchased it in November 2015 for $86. The Item Number was 61282 per the owners manual. Perhaps they still sell it.

Along with the jack, there is a need for an adapter, if the jack point is the side seam.

Although safety says not to add anything in between, but I have 4x4 block of wood with a slot and one side shaved off to match the profile of the scissors jack. It adds about 3.5". I use the same block for other vehicles so I have opt for a low profile jack.
