Is there a way to make highlighting done in Preview visible in other software?
In particular interested in whether it can be seen in Adobe Reader.
Really would like to avoid installing Adobe as it requires frequent updates and seems like a resource hog.
I think this is essentially the reverse of this question: Different ways of displaying documents between Adobe Reader and Preview

I am not quite sure why you have problem seeing in other apps highlighting (and other annotations) made in Preview, but just in case: after you've made all your annotations including highlights, press Cmd + S or File -> Save in Preview app. All your additions shall now be visible in any other apps.
