Krytox 205g0 and Tribosys 3204 are both go-to options for linears - just make sure not to get too much on the center post - a glob at the bottom of the switch may confuse the optical sensors.
:3ildcat on YouTube also often uses a blended mix of Krytox 105 and 205g2 (easier to find in large quantities / less expensive than 205g0), and Jake from switchandclick prefers 105 (thinner of the two) on its own.

This might be a time for RO-59 TM KT. as it will dry to the surface, then you won’t have to worry about a glob building up by the sensor.
